Turn of the Tides

Whenever you or a Planeswalker you control are attacked by one or more creatures, untap each attacking creature that opponent controls and
remove it from combat. Gain control of each
creature untapped this way. Those creatures gain
haste. After this step, you get an additional
combat step. Sacrifice each creature you control
but don't own at end of combat. If it would go anywhere but its owner's graveyard, exile it
instead. Exile Turn of the Tides.
