The Battle of the Heroes

You and target player choose that you control. If
you or the target player chose a Sith creature, that player sacrifices a creature and discards a card to
draw three cards. If you or the target player
chose a Jedi creature, that player discards a card,
gains 4 life and creatures he or she controls get
-1/+2 until end of turn. Those creatures fight.
If one of those creatures is sent to the graveyard
this turn, it can't be exiled from the graveyard.
Players can't cast creature spells until the end
