Quicksilver:Why don't you use Quirion ranger and/or wirewood symbiote?
They allow for nice combat tricks,symbiote can save rofellos,and quirion can save your lands from being wasted.
Also,with rofellos,you have much better mana-producing.
Here's my list,implementing them:
1CC
4 Birds of Paradise
3 Llanowar Elves
1 Quirion Ranger
1 wirewood symbiote
1 spore frog
2CC
1 Rofellos, Llanowar Emissary
1 Viridian Zealot
4 Survival of the Fittest
3CC
3 Troll Ascetic
2 Goblin Sharpshooter
3 Eternal Witness
2 Yavimaya elder
1 Squee, Goblin Nabob
4CC
4 Flametongue Kavu
4 Ravenous Baloth
1 Anger
5CC
1 Deranged Hermit
1 Shivan wurm
1 Genesis
Land
12 Forest
4 Wooded Foothills
4 Taiga

// sideboard
4 Phyrexian Furnace-->madness,reanimator,...

2 gaea’s blessing-->Brainfreeze based combo
1 Masticore-->Angel Stompy, aggro
