Greninja Deck

Greninja doesn’t look like much on paper: it’s not a Pokémon ex, it needs to evolve twice, its attack only hits for 60, and its HP is pretty low for a Stage 2 Pokémon. But it has enough unique qualities to give it a special niche:

• All its pre-evolutions just need to attack. Greninja itself only needs one extra energy to work, so it is playable in decks with another type of Energy, and even into decks without W in the Energy Zone by using Misty and hopefully hitting one heads to get going.
• Greninja's attack Mist Slash is cheap at just  and hits for a decent 60.
• The Water Shuriken ability is Greninja's best asset. Once per turn, Greninja can deal 20 damage to any of your opponent’s Pokémon, Active or Benched, with no energy cost. It can finish off a Pokémon that retreated with a low HP count or deal the exact amount of extra damage needed to secure a KO before or after your attack for turn.

While it’s often played as a secondary engine in Water decks such as Starmie ex, Greninja is now finding success as the centerpiece of its own archetype.
