The Supreme Annihilator

First strike, vigilance, flying
At the beginning of each combat, artifact
creatures you control gain first strike until end of
turn if The Supreme Annihilator has first strike.
The same is true for flying, deathtouch, double strike, haste, hexproof, indestructible, lifelink,
menace, reach, skulk, trample, and vigilance.
When The Supreme Annihilator dies, select
target artifact creature. That creature gains this
card's text in addition to its previous text.
