So my basic idea is stall with a puppet conjurer supported rings of birghthearth costing 3 to put 2 homunculus into play each turn by turn 4, followed by glaze fiend as a 4/5 threat, with Master of Etherium coming between turn 3-5 as either 4/4 or 5/5 growing from there. These are all just stalling long enough to get the mana for Tezzeret to draw and play Sharding Sphinx with hopefully a door of destiny in play an the puppet combo. so each homunculus that falls makes each thopter bigger and vice versa.

This is really a late game deck though. maybe drok has some better thoughts.
