Menegroth Marksman

When Menegroth Marksman enters the battlefield, it patrols, then patrols again.
(Put the top card of your library into your graveyard.
If it's a land you may put it onto the battlefield tapped.
Otherwise put a +1/+1 counter on this creature. Then
repeat this process once.)
{t}: Menegroth Marksman deals damage equal
to the number of counters on it to target
attacking creature.
