Just a powerful but fragile strategy that revolves around making gigantic minions to overpower your opponent.
This is a theorycraft of sorts and a work in progress. So far, this deck actually seems to be working well.
The basic strategy is, play Imprisoned Scrap Imp, Costumed Entertainer, and History Buff to buff Fiendish Imp, Void Terror, Blistering Rot and Midway Maniac in your hand. They all payoff from becoming huge and overpower most midrange decks in Standard.
