Looks strong, it's fast enough that CCYB has problems, including the Explosions. Might want to add a UG or two if you want something effective against RoL/Hope. CHMD and other Timebows probably eat this up (pun intended) with the Elite Fireflies and Octopi as easy targets, not requiring a Firestorm for the initial nomming. I've GotP Time might have an issue with the Explosions, unless it manages to use most of its crucial Hourglasses as fodder.
Definitely a solid idea, especially the original use of Steam Machines in an FG deck.
