Combined with Confusion in the ranks Norin destroys. When you play him, you steal a creature. Then, when your opponent plays a spell or you do that turn, you return him back to your side of the field and steal another creature at the end of the turn. Unless your opponents play no spells or don't attack, you're stealing one creature every turn.

I drew a few sample hands, and was unable to get any forests or methods to get forests for about 4-5 turns on average.
