Sehembia, Oasis Siren

Sehembia, Oasis Siren has ward {1} for each permanent you control but don't own.
{2}{u}{u}{r}{r}, {t}: Gain control of target creature an opponent controls until end of turn. Untap that creature. It gains haste and "Whenever this creature deals combat damage to its owner, create two tokens that are copies of it" until end of turn.
A sweet lullaby for wandering souls doomed not to sleep.
