Deck I've been "evolving" for a while. (I'll see myself out)

The God Hand:

Cloudfin Raptor, Strangleroot Geist, Gyre Sage, Rapid Hybridization, Forest, Forest, Island.

T1: Island, Cloudfin

T2: Forest, Gyre Sage

T3: Forest, Strangleroot Geist. Swing with geist. If geist doen't die, hit him with Rapid Hybridization. If he does, still hit him.

You now have a 3/4 Flying, a 3/4 that taps for GG, a 3/3 and a 3/2 haste on turn three.

Deck Breakdown

Cloudfin Raptor is a solid one drop. Others might say Experiment One, but I like me some evasion.

Burst of Strength is a seriously nice card. Make a creature able to block after attacking AND raise it's p/t permanently? For one green? Also combos nicely with Gyre Sage

Increasing Savagery is a good all-around card. Boost up any card on the battlefield.

Garruk, Primal Hunter provides creatures when you need them, cards when you're down, among other things.

Rapid Hybridization - This card is so useful. Target a pesky bomb, or one of your own that's about to be killed! Either way you come out on top!

Zameck Guildmage - A mini Master Biomancer. Also has nice synergy with Strangleroot Geist

Master Biomancer - Need I say More?

Strangleroot Geist - Great, preferably played on turn 3

Species Gorger - Great Body and "drawback"

Bioshift/Ooze Flux - If one of my creatures is targeted by removal,just use these to create a new creature or pump another one.

Garruk, Primal Hunter, Prime Speaker Zegana, or AEtherling are nice things to ramp into turn 4.
