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, Forest Miasma. An Ability costs you no attack, so you can use it and still swing the same turn.

  2. Keep in mind

    Retreat cost 3. Once it is out front, it stays there. Pack something that moves it another way, or you will burn whole turns discarding Energy.

  3. Keep in mind

    None of the 3,811 tournament lists we have read runs it. That does not make it a bad card — it means we have not seen it on a table yet.

  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.

  5. Keep in mind

    Mark G. It is not among the marks currently accepted in Standard: H, I, and J. A legal reprint may still provide an exception.
