Korina, Beastpath Lookout

Whenever Korina, Beastpath Wrangler attacks, she scouts. (Reveal the top card of your library. If it's a land or artifact put a +1/+1 counter on this creature. Otherwise put the card back on top or into your graveyard.)
Whenever another non-Human creature enters the battlefield under your control you may move any number of counters from Korina onto that creature.
