I myself play 4cc, and you need to fix up a few things. One thing is you need more viable wish targets in the board, by this I mean you need more tools you can use to pull favor to yourself in the game.
3 REB is solid, I would never change, side 2 in and leave one for a wish in the control mirror.
3 BEBs, should be change to maybe one, you'll never really wish for it unless your facing the bloodmoon.
Gush is great sb, it lets you get 2 white out of 1 tundra.
1 Disenchant is great for dealing with random.enchantments, and getting a 2mana artifact destroyer.
1 Vamp is also great, some times you need something on the top of the library, Vamp will do that for ya.
Stifles should be takin out for 1 fire/ice (eats welders) 2 Rack and ruins are great, side one in vs. Artifact.dec and have one wishable.
FTKs are great vs. Madness, your first match is a harsh one and next is great with FTKs in.
Damping Matrix is also good vs artifact.dec, shuts down welders and other artifacts.
(fill up remainder of slots with other good instants)
You should be set! Good luck and have fun
