Dark Moon Calling

Put a hexproof counter on target creature.
It gains enthrall until end of turn. (Whenever
a creature an opponent controls would die, if it
was dealt damage by a source you control with enthrall this turn, instead you may put a thrall counter on that creature and gain control of it.
For as long as that creature has a thrall counter
on it, it can't attack or block and it loses all abilities.)
