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

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

  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 5,427 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 Darkness ×2. Against a Darkness Pokémon, apply that to the damage it takes — it climbs fast. Of the 5,427 tournament lists we have read, 3,370 run at least one Pokémon of that type.
