If you want to continue this, I recomend adding 3 [card]Living Wish[/card]'s.
You could have these in place of Trinisphere. With these you could have [card]Viridian Zealot[/card], [card]Viridian Shaman[/card], [card]Dust Bowl[/card] Etc.. I still don't think mono green could run well as a control deck, It is plasable if you run black for Yawgmoth's Victory, Pernicious Deeds, and Duress's to stop certain decks from shooting right through your locking mechanics.
Also I would suggest -3 Gigapede +3 [card]Troll Ascetic[/card], the trolls are pretty good or so I hear
