Bracyx, Towering Safeguard

Flying, vigilance, hexproof
Creatures your opponents control lose vigilance
and hexproof, and can't gain vigilance or
hexproof.
{g/u}{g/w}{w/u},{t}, sacrifice all enchantments you
control: target creature you control gains your
choice of vigilance or hexproof for the rest of the
game, and Bracyx doesn't untap during
your untap step.
