Sedah, Perdition Prince

Delve (Each card you exile from your graveyard while casting this spell pays for {1}.)
If a creature card with flying was exiled with Sedah, Perdition Prince's delve ability, it gets flying. The same is true for first strike, double strike, deathtouch, haste, hexproof, indestructible, lifelink, reach, trample, menace and vigilance.
Sedah, Perdition Prince 's power and toughness is equal to the creature cards in your graveyard.
