What to make of it

Have a look at what it does well, then at what will get in your way. After that you'll know whether it belongs in your deck.

  1. A strength

    300 HP. Only 1 cards in 30th Celebration carry more.

  2. A strength

    Retreat cost 1. One Energy to discard and it is back on the Bench, which matters a lot on the turn you need to swap attackers.

  3. A strength

    Mega Greninja ex runs it in 1 of the 38 lists we have read, seen across 1 different tournaments.

  4. A strength

    It is a Basic Pokémon. You can put it down on your very first turn, with nothing to evolve through.

  5. Keep in mind

    It is an ex card. The turn it goes down your opponent takes 2 Prizes instead of one, and games do turn on exactly that.

  6. Keep in mind

    Weakness Lightning ×2. Against a Lightning Pokémon, apply that to the damage it takes — it climbs fast. Of the 3,811 tournament lists we have read, 336 run at least one Pokémon of that type.
