i would maybe take out the Curse of Echoes it's a pretty high cost and at that point they're locked down fairly hard anyway. i'd keep it in the sideboard for delver matchups or any other spell-heavy build. but you said you're dying mostly to aggro and an extra Bonfire of the Damned would be great. even if you draw it on turn four or something you can still slow them way down. and if they're some sort of aggro-ramp you can take out a bunch of mana-producing elves or birds or something too.

-3 borderland Ranger +3 Chromatic Lantern Still smooths out your curve and its soooo much better.

I'll test it, see how it works ;).

As extra cushioning for aggro decks, why not throw in 2x Fog Bank ? And I agree with earleir comments, that you need not run 4x Door to Nothingness . I understand that you want to make sure you draw one, but that would be a worry for someone that doesn't have insane drawing power. Which, as you said yourself, you do. So possibly -2 Door to Nothingness and +2 Fog Bank

Well, I have 3x Door to Nothingness right now. No way am I going down to 1 :P.

Not sure what format this is for.

This would currently work in Standard except for Chromatic Lantern . Once RtR hits, you're losing half of your cards to rotation.

This is for the casual, Ima gonna change it right now. It may be casual, but I would prefer to use standard cards xD.
