A strength
Mark J. It is one of the marks currently accepted in Standard: H, I, and J.
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.
Keep in mind
Weakness Psychic ×2. Against a Psychic Pokémon, apply that to the damage it takes — it climbs fast. Of the 5,384 tournament lists we have read, 3,202 run at least one Pokémon of that type.
