I love this, but you die to aggro strategies. Leyline of Singularity would work uber well if you weren't trying to flood the board with Leylines that may have the same name. You could try to be more controlling and add some Counters and board wipes for when SoN isn't online. Though, this deck seems like a bad affinity right now, needing a critical mass of enchantments. You could try to run Honor of the Pure, Greater Auramancy, and Rest in Peace for good stuff.

Serra_Sentinel Hmm. Interesting. I do like these ideas. The problem is that this needs a dedicated enchantment package. You'll need at least 24 enchantments for this ever to work well. Although you can take this in a different direction and run cards like Ghostly Prison, Detention Sphere and the like. And this deck is kinda crap without the power of Enlightened Tutor and Serra's Sanctum. I really do like that Leyline of Singularity though, I completely forgot about it. Maybe a two-of.

Noble Hierarch and the Birds don't do enough in this kind of deck. Sure, they ramp up to the 5CMC combo that this deck wants to have on board, but, that's it. Noble isn't going to get much use of the exalted trigger due to you needing to have an all-out attack plan with the enchantments. Birds is going to remain a 0/1 most of the time.

Yeah, I do know that. I found Trace of Abundance and Fertile Ground to replace that mana ramp. Still, I don't know. It feels like this can go in many different ways, but in the end it just won't be powerful enough. Which is sucky, because this deck would be real cool.
