This invalidates both attackers in night March joltic cuz the effect. Pumkaboo because you cant attack with it with only a DCE. And even if that doesnt matter cuz this stadium is defensive and thus going to be worthless
I don’t think this is good enough, the decks are not designed to leave the opponent on 40 hp or less, you try to 1HKO or 2HKO consistently, not doing damage for the oponent to survive with 40 hp. Furthermore, even if you manage to get the opponent down to 40 hp, the opponent can counter stadium, retreat or acerola to heal up and attack with another Pokemon. Just not worth to run this over other stadiums like unmaned power plant or fighting dojo.
