Flying, Deathtouch, lifelink, Ward - Pay 6 life
Pay 6 life: Search target player's library for a card
and exile it face down. Then, that player shuffles.
You may look at and play that card for as long
as it remains exiled.
Wretched— At the beginning of each end step,
if you have less life than half your starting life
total, create a treasure token, draw a card,
and lose a life.
