The effect would be something like: Option 1: After making a succesfully basic attack this champ atk becomes 0 for X turns. Option 2: This champ atk is permanently reduced by 2 whenever it succesfully make a basic attack. It's supposed to be a negative ability to reduce the cost of having lots of dmg.
option one seems legit. slamming all his power into one full-on ONE PUNCH MAN styled op action power hero butt slam. thinking 20+-30 damage( using power attack (3) with some hunter ability) without buffs
