Boethiah, Prince of Treachery

Indestructible
Boethiah, Prince of Treachery can't attack or
block unless your devotion to red and white is
seven or greater.
Whenever you cast your second spell each turn,
gain control of target creature until end of turn.
Untap that creature. It gains haste. Sacrifice it
at the beginning of the next end step.
"Skyrim is a beautiful and harsh mistress, but her
people cling to such a petty notion of honor."
