So you want a card that's similar to Stat Wipeout, but requires less energy and only removes attack? Well, for now, just either use Stat Wipeout, build up defense or kill your opponent before it kills you.
NEW LOOT CONCEPT ADDED TO ARENA (too lazy to change version number). Duplicated rings will turn into 2,000 Pixels. The 3 new ring types now drop from monsters at an extremely rare rate (I mean, 0.09% chance to get Ring of Revenge when you pick up a ring).
