What he said.

Also, an advice on accelerators. If you are using accelerators in the form of creatures, it's USUALLY to ramp to 3 mana on turn 2. Only do that if your turn-two play with 3 mana can CRUSH an opponent (and Doran IS one of those plays, yes), and if you're gonna do, then play a set of accelerators, at least (so, AT LEAST 4 Birds of Paradise). Timber Protector is more cool than actually GOOD, I'd advise running 4 Harbingers and Primal Command (and possibly Fertile Ground, amazing with Garruk), and play a bunch of singleton Treefolks that can be tutored according to your needs, like Unstoppable Ash, Timber Protector, etc. Oh, and fit Profane Command in there somewhere.
