When Treacherous Bride enters the battlefield,
target opponent gains control of it.
Corrupt (You can only gain life from a spell or effect
that causes damage or loss of life. You must pay 1 life

At the beginning
of your upkeep, target opponent loses 1 life, you
gain 1 life, and you gain a taint counter.
A Scorpion may give one a gift onet one cannot refuse.
Seeming as sweet as honey, yet as deadly to a house
as nightshade is to a man.
