Steal Everything

Not my usual style (it's kinda mean); this deck runs a ton of steal effects.
The creature type changers (Amoeboid Changeling, Imagecrafter, etc.) are to change a creature into a Sliver and steal with my general (Sliver Overlord).
The current version of the deck has no mana ramp; the deck can usually steal enough rocks, etc. to function. Probably a mistake, but I'm trying it this way for now.
