This card OWNS! I love shutting out green since everyone in my playgroup has an elf deck that's almost identical to one another: Priest of Titania, Heedless One, Genesis Wave, Wirewood Lodge, etc. Use something like the above mentioned or Sleight of Mind to hose the color creatures of your choice. Then run something like Seedborn Muse and/or Quest for Renewal and you can completely ignore it's double-edged effect and spank your opponent.

Read this carefully--it says nothing about untapping your nongreen creature more than once per upkeep...I've used this with alter reality and priest of titania for infinite mana.
