Permanents you control don't untap during your
untap step. Whenever a werewolf or a wolf you control deals damage to an opponent or a
permanent an opponent controls, untap half that
many permanents rounded down.
{t}{b}{g}{u}: Take an extra turn after this one. Pay
twice X life and draw X cards where X is the
amount of wolves and werewolves you control.
Round down each time.
