Sharkey, the Boss

When Sharkey, the Boss blocks a creature,
you may gain control of that creature until end
of turn.
Whereas Curunir was cast down, and utterly
humbled, and perished at last by the hand of
an oppressed slave, and his spirit went whither-soever
it was doomed to go, and to Middle-earth, whether
naked or embodied, came never back.
