I'd like to see your decklist, because from your description, it doesn't play anything remotely like my deck. Especially because you mention Deed. I can't play more than 2 colors by choice, because otherwise I irreparably screw my manabase. This deck isn't based around power, it's based around redundancy. Also, tutors? wtf?

Cunning Wish is nice and cute, and I used to have it in the deck, but ultimately I don't want a Wishboard, I want good cards. The deck already has tons and tons of mid-late game cards, Cunning Wish is just superfluous.

Vedalken Shackles is probably the weakest card in the deck, its main function is to act as a Crucible/Factory infinite blocker against generic aggro decks, and means they have to really overcommit their board if they want to get in damage against creatures. Also it creams Landstill, especially in conjuction with a Explosives at 0.
