Faceoff !

Both you and target opponent put into play a
Ninja from your respective hands, then they
fight until at least one of them is destroyed
(players do not recieve any damage or gain any
life and Ninjas can use their Jutsu abilities
before each fight if able).
Exile any destroyed Ninja. Any Ninja that
remains on the battlefield goes back to its
owner's hand and can be played for free next
turn.
