Another Brother

Target creature gains undying until end of turn.
(When it dies, if it had no +1/+1 counters on it,
return it to the battlefield under its owner's
control with a +1/+1 counter on it.)
Then it fights target creature an opponent
controls. (Each deals damage equal to its power
to the other.)
Jeffy had no idea how strong some family ties
(or members) could be when he shot the orcish
horse thief. Now he knows well.
