The Three Dreamers

Vigilance, Trample, Deathtouch
Whenever a creature you deals combat damage to another player, return a creature with mana value X or less to the battlefield. It becomes Dreamshifted. (Dreamshifted permanents cannot block, be blocked or be the target of abilities of permanents which are not Dreamshifted). Whenever a creature card leaves your graveyard, choose one:

Target creature you control fights target creature you don't control.

Place a stun counter on target creature.
