Mordekaiser

Delve (Each card you exile from your
graveyard while casting this spell pays for {1}.)
If a creature card with flying was exiled
with Mordekaisers delve ability, Mordekaiser
has flying. The same is true for first strike,
double strike, deathtouch, haste, hexproof,
indestructible, lifelink, reach, trample, and
vigilance.
