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

    It has an Ability, Boom Boom Groove. An Ability costs you no attack, so you can use it and still swing the same turn.

  2. A strength

    Seaking runs it in 55 of the 55 lists we have read, seen across 47 different tournaments.

  3. A strength

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

  4. Keep in mind

    Weakness Fire ×2. Against a Fire Pokémon, apply that to the damage it takes — it climbs fast. Of the 3,811 tournament lists we have read, 914 run at least one Pokémon of that type.
