Whenever this creature attacks while you don't control another Dinosaur, put a stun counter on it. (If a permanent with a stun counter would become untapped, remove one from it instead.)
原文If you didn't control another Dinosaur when you declared Pugnacious Hammerskull as an attacker, it doesn't matter whether or not you control one as its ability resolves. You'll still put a stun counter on Pugnacious Hammerskull.
