Seth, Artificial Perfection

When you cast Seth, Artificial Perfection, you
may exile any number of creature cards from
your hand and graveyard and put a data counter
on each of them.
As long as card you own in exile with a data
counter has flying, Seth, Artificial Perfection has
flying. The same is true for first strike, trample
deathtouch, double strike, haste, hexproof, reach,
indestructible, lifelink, menace, and vigilance.
