Always felt great casting Bump in the Night, but then gatecrash happened. Black got pushed out, as white was now the clearly superior color. With Boros Charm and Lightning Helix (not to mention the glorious Kor Firewalker for the mirror) how could I argue. Then Dragons of Tarkir came and we got Atarka's Command which was worth going three colors for since it frequently said deal 5 damage (or more), it could slide in 1:1 for Skullcrack, and it gave us Destructive Revelry to boot for the sideboard. Poor black was left to the sidelines. I wanted to go back to casting those sorcery speed player only bolts. Unable to find a good reason to cut either white or green from the deck I'm getting greedy and trying out a 4 color brew. I figure on average I'm taking an addition 3 more damage from my lands a game, but I think I'm speeding the deck up a 'half turn' on average. I'm not sold on the idea but I wont stop day dreaming about it until I have tested it thoroughly.
My Sideboard is a mess at this point I change it daily (Leaving it static on Tappedout for now)Black doesn't really get us too much, at this point I am only running 1 Rakdos Charm (Rain of Gore, Abrupt Decay, kolagan's command just don't seem to do enough).
White is always an all star in the sideboard
Green provides a great multitool w/ the 'D'
I would love comments and suggestions and about sideboard, card quantities, alternate mana bases.
Speaking of alternate mana bases, if I decide that I don't want to run Searing Blaze's, I might decide on a 8-12 fastland package + 2 mountains + a small (6-10) fetch/shock package. And maybe run myself some Shard Volleys to keep it moving. Don't think it's a terribly great idea, but it's an idea.
