Nice write up! Nature has so many good cards, it's not the end of the world if you don't have the absolute best. I do love Jag Staffs.

I particularly like your inclusion of Sudden Bloom. You already have 7 (!) board buff cards to reward yourself if you get wide, but SB gives you a win condition even if you only have 1 creature in play. You also have enough non-confused creatures to make it workable. My only concern is that you might want to scale back your board buffs to 5 or so and get some 4+ HP creatures in the deck. Rabid Bears come to mind.

Anyway, nice job!
