Gessell

Gessell has first strike if a creature you control or a creature in your graveyard has first strike. The same is true for flying, deathtouch, double strike, haste, hexproof, indestructible, lifelink, menace, reach, skulk, trample, and vigilance.
As long as Gessell is on the battlefield, it has all activated abilities of all creatures you control and all creature cards in your graveyard.
