Card Text:
Treason
Gain control of target creature under opponent's control. Creature may attack or use special abilities as soon as it comes over to your side. Controller of target creature may counter Treason by paying X life, where X is the toughness of target creature; this creature is then buried. Effects that reduce or redirect damage cannot prevent this loss of life. Bury target creature if Treason leaves play.
"Suspicion all our lives shall be stuck full of eyes/for treason is but trusted like the fox."
