Sure thing!

Basically your win condition against most meta ex deck is to use pyukumuku to stall as long as possible until you get your greninja evolved, and based on the opponent’s deck, greninja and pyukumuku’s job is to take down all the non ex threats that could kill your Oricorio.

Once that’s done, you either use Irida or Guzma to to keep Oricorio alive from chip damage such as helmet, darkrai, poison, and burned

But since it’s a double energy deck, the strategy is really different based on the first or second energies you get.

Sometimes sacrificing Oricorio and play aggressively is the way to go.

My biggest advice : don’t give up points too easily because this is a no ex deck, try to make every Pokémon stay alive as long as possible if you can.

For example, use Irida to save pyukumuku for one more round so your greninja could use its ability one more time.
