Tim's Dire Warning

At the beginning of every combat on each turn, opponents must pay {1} for each Rabbit creature you control that's attacking or blocking this turn. If they don’t, Rabbit creatures you control gain double strike until end of turn.'

“I warned you, but did you listen to me? Oh, no, you knew it all, didn’t you? Oh, it’s just a harmless little bunny, isn’t it?”-Tim the Enchanter
