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

    Seaking runs it in 3 of the 75 lists we have read, seen across 3 different tournaments.

  2. A strength

    Mark H. It is one of the marks currently accepted in Standard: H, I, and J.

  3. Keep in mind

    Retreat cost 4. Once it is out front, it stays there. Pack something that moves it another way, or you will burn whole turns discarding Energy.

  4. Keep in mind

    It is a Stage 2. You have to come through Thwackey to get here, or find a Rare Candy to skip the middle step.

  5. Keep in mind

    Weakness Fire ×2. Against a Fire Pokémon, apply that to the damage it takes — it climbs fast. Of the 5,417 tournament lists we have read, 1,251 run at least one Pokémon of that type.
