Vashar Ambush

As an additional cost to cast this card you must either pay 5 life or sacrifice 2 non-token creatures.
Target a creature an opponent controls then, Tap it and Ensnare 1.
(Ensnare: Take control of target creature and place X -1/-1 counters on it.)
It was here the Vashar ambushed the agent, and
made of him an unwilling ally, at great cost.
