Since this deck is really aggressive, you really need to drop a Bogle or a Scout on turn 1. Turn 2, throw an Ethereal Armor or an Aqueous Form, or both, on your creature and swing with a 2/2 or a 3/3 unblockable. Turn 3, throw a Rancor, a Lifelink, a Spider Umbra, or a Spectral Flight on your creature and swing again. By turn 3 you can be swinging with a really big creature if you have multiple enchantments, especially if one of them happens to be Ethereal Armor.
This deck has been around for a while, but I have never seen anyone run Unstable Mutation, either in the main or side. Sometimes I run it in the main, but you have to be careful to use it as a finisher, because if it's out for more than 1 or 2 turns it starts to undo the buffs from your other enchantments.
I've considered running more creatures, possibly adding 3 or 4 of Bassara Tower Archer or Sacred Wolf and cutting some of the enchantments down to allow for space, but the deck as it stands is pretty consistent, plus I've already sideboarded Geist of Saint Traft, just in case I find myself with a handful of enchantments and no target.
Also, things to look out for: Since this deck runs only 16 creatures, make sure you pull one of them in your open hand, otherwise you're gonna be sitting there with a bunch of enchantments in your hand and nothing to cast them on. Also, be careful if you know you're running against a blue deck, because you don't want them to Mana Leak the only creature you have in your hand. The ideal opening hand, I've discovered is: 2-3 lands, Slippery Bogle/Gladecover Scout, and 3 enchantments (hopefully one of them being Ethereal Armor/Aqueous Form).
