Mega Greninja ex does 260 a turn: Mortal Shuriken places 60 anywhere, then Ninja Spinner hits for 200 and returns a [W] Energy to hand to fuel next turn's Shuriken. Never run out of Water Energy in hand.

Difficulty: HardPrizes: Mega Greninja gives 3; Greninja ex, Meowth ex, Fezandipiti ex 2

Your turn-2 goal

  • Mega Greninja ex Active via Rare Candy on Froakie, with [W][W] or Neo Upper Energy.
  • At least one Basic [W] Energy in hand for Mortal Shuriken, ideally two.
  • A second Froakie or Frogadier on the Bench for the next attacker.
  • Surfing Beach in play or Air Balloon attached so you can pivot freely.

Your attackers

Mega Greninja exNinja Spinner

120; 200 returning a [W] to hand

Your main attack every turn. Skip the return when 120 already KOs and you want to keep Energy on board.

Mega Greninja exMortal Shuriken

6 damage counters on any Pokémon

Every turn it is Active and you have a spare Basic [W] in hand: finish a Benched Pokémon or set up a 2-turn KO.

Greninja exShinobi Blade

170 and search your deck for a card

One-Energy attack that also fetches your missing piece. Against [F]-weak ex it does 340.

Greninja exMirage Barrage

120 to 2 Pokémon; discard 2 Energy

Two-Prize turns against Basics and Stage 1s with 120 HP or less.

FrogadierSummoning Jutsu

Search your deck for up to 3 Pokémon

No Supporter for the evolution pieces, or rebuilding after a KO.

Key decisions

  • Shuriken first, attack second. Place 60 before Ninja Spinner: 60 + 200 = 260 KOs any 260-HP target, or leaves a big one in range of next turn's 260.
  • Count your Water Energy. For Shuriken plus a 200 Ninja Spinner each turn you need two Basic [W] in hand. Count before Lillie's Determination, and recover with Night Stretcher or Energy Retrieval.
  • Neo Upper Energy on Mega Greninja. It pays [W][W] alone, so the [W] you attach each turn can return to hand for the 200 version.
  • Greninja ex is not a [W] Pokémon. Surfing Beach can't swap it in; use Air Balloon, Switch or a retreat instead.
  • Bench Meowth ex and Fezandipiti ex only when needed. Mega Greninja (3) + one 2-Prize ex + one single-Prizer is all six of their Prizes.

Common mistakes

  • Leaving Mega Greninja on the Bench with no way to get Active: no Shuriken that turn.
  • Burning every [W] on Shuriken and having nothing to attach for next turn's attack.
  • Benching several Froakie (70 HP) against spread damage: one spread attack takes multiple Prizes.
  • Playing Wally's Compassion without a plan to reattach: it returns all of Mega Greninja's Energy to your hand.

Versions

Dudunsparce engine

The standard partner: Run Away Draw for cards, plus Dudunsparce ex's Tenacious Tail against boards of Basic ex.

Dragapult partner

Dreepy, Drakloak and Dragapult ex add Recon Directive draw and Phantom Dive's 6 counters on top of Shuriken.

Ignition Energy and Dawn

Ignition Energy plus one [W] pays Mirage Barrage in one turn; Dawn grabs Froakie, Frogadier and Mega Greninja together.

Matchups

Mega Greninja vs Dragapult

An uphill fight: Dragapult ex has 320 HP and no Weakness, so one Ninja Spinner never KOs it. You win only if Mirage Barrage clears Dreepy and Drakloak before the Dragapult ex line is built.

Their plan

  • Phantom Dive: 200 to your Active plus 6 counters on your Bench. Two hits KO Mega Greninja ex (350) for 3 Prizes; Froakie (70) survives one spread unless already damaged.
  • Risky Ruins: every Froakie you Bench takes 2 counters (50 HP left), so the 6 counters of Phantom Dive KO it. Fezandipiti ex is [D] and is not hit.
  • Budew and 4 Crushing Hammer: Itchy Pollen locks Rare Candy, Poffin and Poké Pad; Hammer discards the [W] your attackers need.
  • Munkidori: Adrena-Brain moves 3 counters each turn, and Mind Bend is [P], so it does 120 to Greninja ex (weak to [P]).

Your prize plan

  1. Mirage Barrage first. Greninja ex does 120 to 2 Pokémon: KOs Dreepy (70), Drakloak (90), Munkidori (110) or Budew (30). Two Prizes a turn before Dragapult ex exists.
  2. Shuriken Budew. Mortal Shuriken's 6 counters KO Budew (30) and end the Item lock. They do not KO Dreepy (70) alone.
  3. Two-turn KO on Dragapult ex. Shuriken it (60) on the Bench, then next turn Shuriken + Ninja Spinner returning a [W]: 60 + 60 + 200 = 320, exactly its HP.
  4. Shinobi Blade their ex. Fezandipiti ex and Meowth ex are weak to [F]: Greninja ex does 340 to either in the Active, KO for 2 Prizes.

Mirage Barrage last turn + Ninja Spinner320 · KO
Shuriken last turn + Shuriken + Ninja Spinner320 · KO

Don't

  • Benching several Froakie with Risky Ruins in play: each sits at 50 HP and one Phantom Dive KOs them in a row. Play Surfing Beach to replace the Ruins first.
  • Leaving all your [W] attached against 4 Crushing Hammer. Ninja Spinner returns one to hand, where Hammer can't touch it and it pays next turn's Shuriken.
  • Counting on Surfing Beach to bring in Greninja ex: it is [F], not [W]. Use Air Balloon or Switch to move it.

Key turn

  • Your turn 2: Rare Candy into Greninja ex before Budew lands, then Mirage Barrage the two Drakloak. If they keep their Drakloak, Phantom Dive arrives every turn and you fall behind.
  • The turn after Unfair Stamp: they reset your hand to 2 cards. Keep a [W] attached instead of in hand when they are about to lose a Pokémon.

If they play…

Shaymin

Flower Curtain stops Mirage Barrage on their Benched Dreepy and Drakloak. Mortal Shuriken still places its counters there.

Dudunsparce ex

Tenacious Tail does 60 for each of your Pokémon ex. Mega Greninja ex, Greninja ex and Meowth ex in play already make 180.

Team Rocket's Watchtower

Your Meowth ex and Dudunsparce lose their Abilities. Draw with Lillie's Determination and Frogadier's Summoning Jutsu instead.

Mega Greninja vs Basic Box

Greninja ex's Shinobi Blade KOs Mega Kangaskhan ex through Weakness for one Energy, but their Psychic attackers hit Greninja ex for double and their snipes slow your Stage 2s. Trade your 3-Prize KOs for their 2-Prize answers.

Their plan

  • Psychic hits on Greninja ex (weak to Psychic): Eon Blade (200) and Love Resonance (200 when you share a type) both become 400, a KO.
  • Rapid-Fire Combo: 200 + 50 per heads. It needs 3 heads to KO Mega Greninja ex (350), and Run Errand draws 2 while Kangaskhan is Active.
  • Raging Bolt ex: Bellowing Thunder does 70 per Basic Energy discarded; 5 Energy is 350, a KO on Mega Greninja ex.
  • Bench snipes: Cruel Arrow (100) and Torrential Pump (120 to the Bench) KO Froakie (70) or Frogadier (100) before they evolve.

Your prize plan

  1. Shinobi Blade the Kangaskhan. 170 ×2 = 340 for one [W] KOs Mega Kangaskhan ex (300) for 3 Prizes. Same KO on Meowth ex (170) and Fezandipiti ex (210).
  2. Through Hero's Cape (400 HP): Mortal Shuriken first with Mega Greninja ex Active, retreat for free with Air Balloon, then Shinobi Blade: 60 + 340 = 400.
  3. Mega Greninja ex for the other ex. Ninja Spinner 200 + Shuriken 60 = 260 KOs Latias ex (210), Iron Crown ex (220), Iron Leaves ex (220) and Raging Bolt ex (240).
  4. Shield the Stage 2 line. Bench only the Froakie you can evolve next turn; Shaymin stops Cruel Arrow and Torrential Pump damage on them.

Mortal Shuriken + Shinobi Blade, Hero's Cape attached400 · KO
Ninja Spinner (returning a [W])200
Tenacious Tail (5 of their ex in play)300 · KO

Don't

  • Shinobi Blade into Latias ex or Iron Crown ex: both resist Fighting (−30), so it only does 140. Use Mega Greninja ex there.
  • Leaving Greninja ex Active when they have Latias ex or Enamorus ready: 400 damage, 2 Prizes.
  • Benching extra ex (Meowth ex, Fezandipiti ex): each is 2 Prizes for Boss's Orders, and Enamorus shares a type with most of them.

Key turn

  • Your first Kangaskhan KO. Shinobi Blade takes 3 Prizes; even if Eon Blade answers on Greninja ex, you stay a Prize ahead.
  • When Chien-Pao's Snow Sink discards your Surfing Beach, keep Air Balloon on Mega Greninja ex so you can still pivot for Mortal Shuriken.

If they play…

Koraidon ex

Impact Blow (200) ×2 KOs your Meowth ex or Fezandipiti ex. Koraidon (230) falls to Ninja Spinner + Mortal Shuriken (260).

Jamming Tower

Your Air Balloon stops working, and so does their Hero's Cape. Pivot with Surfing Beach or Switch.

Unfair Stamp

After your KO they reset you to 2 cards. Keep a [W] attached so you can still attack.

Mega Greninja vs Mega Excadrill

Both Megas survive one hit unless boosted. You two-shot Excadrill with 260 a turn and one-shot their Genesect ex and Mega Skarmory ex; they need Kieran or Gravity Mountain to one-shot Mega Greninja.

Their plan

  • Maximum Drilling: 330 with 5 Energy. Mega Greninja ex (350) survives, but Kieran makes it 360 and Gravity Mountain drops you to 320: both KO.
  • Metal Maker: each Metang attaches every Metal Energy in the top 4 cards, so a fresh Excadrill can be charged in one turn.
  • Sonic Ripper (Mega Skarmory ex): 220 to any Pokémon. Benched Meowth ex (170), Fezandipiti ex (210) and Frogadier die.
  • Hero's Cape and Jumbo Ice Cream: Excadrill goes to 440 HP and heals 80 when Active with 3+ Energy.

Your prize plan

  1. Hit the Metang line early. Mirage Barrage does 120 to 2: Beldum (70), Drilbur (70) and Metang (100) all die, and Metal Maker slows down.
  2. Ninja Spinner + Mortal Shuriken = 260 a turn. That KOs Genesect ex (220) and Mega Skarmory ex (260). Boss's Orders the Skarmory after it attacks: 3 Prizes.
  3. Excadrill takes two turns. 260 + 260 beats Jumbo Ice Cream, even on a Hero's Cape Excadrill (440 + 80 healed = 520). Never switch targets halfway.
  4. Surfing Beach over Gravity Mountain keeps Mega Greninja at 350, so a 330 Drilling without Kieran doesn't KO it.

Ninja Spinner + Mortal Shuriken vs Mega Skarmory ex (260 HP)260 · KO
Mirage Barrage vs Metang (100 HP) + Beldum (70 HP)120 each · 2 KOs

Don't

  • Benching Meowth ex or Fezandipiti ex for no reason. Sonic Ripper takes 2 Prizes from the Bench with no gust.
  • Running out of Water Energy in hand. Each turn needs one to attach and one to discard for Mortal Shuriken.
  • Leaving Greninja ex Active into a charged Excadrill. 330 KOs it (310 HP) for 2 Prizes.

Key turn

  • The turn their first Excadrill reaches 5 Energy. Have it at 260 damage already, or have your second attacker built before Drilling lands.
  • If Mega Greninja survives a Drilling, Wally's Compassion heals it fully and returns its Energy to your hand to fuel the next Shuriken.

If they play…

Gravity Mountain

Mega Greninja drops to 320 and Greninja ex to 280: Drilling one-shots both. Replace it with Surfing Beach right away.

Empoleon ex

320 HP and takes 60 less after Iron Feathers. Mortal Shuriken is an Ability, so Emperor's Stance doesn't stop it.

Battle Cage

Mortal Shuriken can't put counters on their Bench. Save it for the Active, or replace the Stadium with Surfing Beach.

Mega Greninja vs Slowking

Slowking trades 1-Prize attackers into your 3-Prize Megas and its Trifrost wipes your Froakie line. Your outs: Shinobi Blade one-shots their Kangaskhan, and Mirage Barrage takes two Slowpoke-line Prizes a turn.

Their plan

  • Trifrost (copied): 110 to 3 Pokémon. Benched Froakie (70) and Frogadier (100) die; an Active Greninja ex takes 220 from Weakness.
  • Greninja ex is weak to Psychic, and copied attacks are Psychic. Metallic Hammer does 300 (it survives at 10); with Brave Bangle, 360 KOs it.
  • Thunder Raid (Zeraora): 210 to a Benched ex. Meowth ex and Fezandipiti ex die; Greninja ex (310) and Mega Greninja ex (350) survive.
  • Slowking gives 1 Prize. They need only two Mega Greninja KOs to win.

Your prize plan

  1. Turn 1: Shaymin on the Bench (Poké Pad). Flower Curtain stops Trifrost damage to your Benched Froakie and Frogadier.
  2. Shinobi Blade the Active Mega Kangaskhan ex. 170 ×2 for Weakness = 340 against 300 HP: 3 Prizes for one Water Energy.
  3. Mirage Barrage: 120 to the Active Slowking (120) and a Benched Slowpoke (80). Two KOs, and their attacker supply runs dry.
  4. Boss's Orders Latias ex (210): Ninja Spinner + Mortal Shuriken (260) KOs it, and Kangaskhan loses its free retreat.

Ninja Spinner (no Energy returned) vs Slowking (120 HP)120 · KO
Mirage Barrage: Active Slowking + Benched Slowpoke (80)120 each · 2 KOs

Don't

  • Leaving Greninja ex Active after its attack when they have Brave Bangle. Surfing Beach can't move it (it's Fighting type): use Air Balloon or Switch.
  • Benching Meowth ex or Fezandipiti ex while Zeraora can be copied: 2 free Prizes.
  • Benching three Froakie before Shaymin is down. One Trifrost erases your whole evolution line.

Key turn

  • Their turn-2 Trifrost. If Shaymin is in play first, it only hits your Active and you keep both Greninja lines.
  • The turn Kangaskhan is Active for Run Errand: have Greninja ex ready with one Water Energy. That KO is half your Prizes.

If they play…

Annihilape

Ghostly Blow does 100 (200 on Greninja ex) plus 5 damage counters on your Bench. Shaymin doesn't stop counters.

Brave Bangle

+30 against your Active ex before Weakness: Metallic Hammer becomes 360 on Greninja ex and 180 on Mega Greninja ex.

Drapion

Hazardous Tail copied: 100 plus Paralyzed and Poisoned. Keep a second attacker ready to take over.

Mega Greninja vs Dragapult Blaziken

Blaziken ex is weak to [W] and falls to a full Ninja Spinner, but they have two 320 HP attackers that each take two of your attacks to trade into Mega Greninja ex. Spread on your Bench decides it.

Their plan

  • Phantom Dive and Smolder-sault: 200 each. Two hits KO Mega Greninja ex (350) for 3 Prizes; Phantom Dive also puts 6 counters on your Bench.
  • Seething Spirit attaches a Basic Energy from their discard each turn: they recover fast after a KO, so a lone Smolder-sault turn is not a free turn for you.
  • Chi-Yu: Ground Melter does 120 with a Stadium in play and discards your Surfing Beach, so Mega Greninja ex can lose its pivot.
  • Munkidori: Mind Bend is [P] and does 120 to Greninja ex (weak to [P]); Adrena-Brain adds 3 counters to any target.

Your prize plan

  1. KO Blaziken ex first. Ninja Spinner returning a [W] does 200, doubled to 400 against Blaziken ex (320). Without returning it, 240 + Shuriken 60 = 300 is not enough.
  2. Mirage Barrage the Dreepy line. 120 to 2 Pokémon KOs Dreepy (70), Drakloak (90) or Munkidori (110) before they become Phantom Dive.
  3. Ninja Spinner their small [R] Pokémon. Torchic (70), Combusken (100) and Chi-Yu (110) are weak to [W]: even 120 becomes 240, KO.
  4. Dragapult ex needs two turns. Shuriken it first, then 60 + 200 next turn: 320, exactly its HP.

Shinobi Blade (Greninja ex is [F])170
Ninja Spinner, keeping the [W]240
Ninja Spinner (keep) + Mortal Shuriken300
Ninja Spinner, returning a [W]400 · KO

Don't

  • Attacking Blaziken ex with Greninja ex: it is [F], so Shinobi Blade does only 170. Mega Greninja ex's [W] attack is the one that doubles.
  • Relying on Dudunsparce or Meowth ex when Team Rocket's Watchtower is in play: both are [C] and lose their Abilities.
  • Leaving Greninja ex Active against a ready Munkidori: 120 from Mind Bend plus Phantom Dive's spread takes it down fast.

Key turn

  • The turn after Smolder-sault: that Blaziken ex can't attack. KO it with a 400 Ninja Spinner so Seething Spirit never gets value from it.
  • When Chi-Yu discards Surfing Beach: have Air Balloon or Switch ready, or Mega Greninja ex can't reach the Active for Mortal Shuriken.

If they play…

Lillie's Clefairy ex

Full Moon Rondo is [P] and doubles against Greninja ex. Fairy Zone also makes your Dragapult partner, if you run it, weak to [P].

Risky Ruins

Their Torchic and Dreepy enter at 50 HP: Mortal Shuriken alone KOs them on the Bench. Your Froakie suffer the same.

Area Zero Underdepths

With a Tera Pokémon in play, a player can Bench up to 8. More targets for Mirage Barrage; replace it with Surfing Beach.
