Gregor Mendel

{t}, sacrifice a nontoken creature you control:
Create X 1/1 green plant creature tokens,
where X was the sacrificed creature's mana
value. If the sacrificed creature had first strike,
put a first strike counter on target plant token.
Then do the same for flying, deathtouch, double
strike, haste, hexproof, indestructible, lifelink,
menace, reach, skulk, trample, and vigilance.
