Ironskull, the Dark Master

Lifelink, Flying, Teleport (Whenever this creature would die, you may pay five life. If you do, put a +1/+1 counter on it and put it into The Realm.)

Voice of the Otherworldly-At the beginning of each combat, creatures you control gain first strike until end of turn if a creature you control has first strike. The same is true for flying, deathtouch, double strike, haste, hexproof, indestructible, lifelink, menace, reach, trample, vigilance and swampwalk.
