I don't want to be a jerk, but Collosus of Akros is garbage. Any good deck will keep you off your mana acel since you rely solely on creatures for your mana. Making you play on curve is DEVASTATING. Where are the
sylvan caryatid for the hexproof mana dork?
Fog is terrible also. It is strictly defensive. There is no use for
fog in a game where you are on the offensive, and it becomes a
dead card. 2
plummet? Why are you sideboarding against flyers in the main deck? You're already 2 cards long in the deck as it is, why are you diluting your deck from getting the cards you need when you need them?
Why no Polukranos? Polukranos is FAR better than the collosus of Akros. a 5/5 for 4 is far more
dangerous than a 10/10 for 8. and if you have the mana like you say you do, then monsterousing Polukranos with all that mana, and killing all their blockers and just attacking for lethal with him is the same... Polukranos has WAY more upside and none will very rarely be in your hand waiting on mana. Besides that, it has a really awesome synergy with the
Bow of Nylea.
I would also consider putting in Garruk,
Call of beasts to keep your hand full of threats in the late game.
Just some friendly advise.
