I may be misremembering rules, but if you have equipment or I think an effect like Overwhelming Stampede up that increases her power by 5, you can use Channel to get infinite life and infinite mana.

Also, Overwhelming Stampede, Soul's Majesty, Garruk Primal Hunter are good in general, but obviously not usable with B/W.

Necrotic Ooze is also hilarious with Tree of Redemption.
