Mirror Packmaster

When Mirror Packmaster enters the battlefield,
create a 2/2 green wolf creature token. If Mirror
Packmaster is tapped and attacking, the token is
too, and its exiled at the end of combat.
Myriad (Whenever this creature attacks, for each
opponent other than defending player, you may create
a token that's a copy of this creature tapped and
attacking that player or a planeswalker they control.
Exile the tokens at the end of combat.)
