Sofi

Courtesan Creatures can not attack or block and
can not be sacrificed.
When Sofi enters the battlefield, target
opponent gains control of her.
At the beginning of your upkeep sacrifice a
permeant unless you pay {4}.
Whenever a creature attacks you, that creature
gains; Whenever this creature deals combat
damage to an opponent, you may draw a card.
"Oh my! Aren't you big and strong?"
