Cool! Go Landfall! I ran a very similar landfall deck, though without the griffons. I never really got much mileage out of them. Territorial Baloth really isn't worth the cardslot. Its lack of trample is crippling; The other one, Woodcrasher is awesome. I swung for 60 in 1 turn with it once! I heartily recommend dropping the Territorial Baloths for a couple Emeria Angel. They are fantastic and really make your opponent think about how to deal with all those 1/1 birds. They make good chump blockers in a pinch, too.
Here's my deck: http://deckbox.org/sets/12434 (ignore the explorers scope... they need taking out!)
