Kaylin the Renegade

Flying
When Kaylin the Renegade enters the battlefield,
if you do not control a creature named Wulfric,
create Wulfric, a legendary 3/3 green wolf
creature token with "Whenever this creature
attacks, flip a coin. If you win the flip, Wulfric
deals 4 damage to target opponent. If you lose the
flip, Wulfric deals 4 damage to you."
Actually, his bite is worse than his bark.
