Have you considered Urza's Incubator, Savage Ventmaw, and Aggravated Assault? Savage + Assault = unlimited attacks.

I'm not a fan of infinite combos, but Savage Ventmaw seems good on its own anyway, will give both that and agrivated assault consideration. Urza's Incubator I am almost certainly going to get though, just not sure what to cut for it...

Neurok Stealthsuit, Lotus Petal, Torrent of Souls, Vigor Mortis, Thunder Dragon, and Mirrowing Dragon seem like the weakest cards in this deck at the moment.

Mirrorwing Dragon is there for the lolz if someone tries spot removal on my commander, it is pretty situational I'll grant you. Some of the others could go, I must admit I don't get much use out of the stealth suit. I ordered Urza's Incubator from eBay, so definitely going in there somewhere.

The issue with Mirrorwing Dragon is that its effect triggers when the spell is cast. So if an opponent casts a spell and targets your commander and you respond by turning him into Mirrorwing, Mirrorwing's effect won't trigger because the spell is already cast and he wasn't there to see it.

Damn, obvious when you point it out. Not sure how I missed that. So the only real reason for Mirrorwing Dragon is a target for your own pump spells.
