This is basically the same as my deck with -1 tower, supernova, miracle, hourglass, and quintessence.
Gases are good damage if you have the quanta to make them, but most of the time the destroyers will do sufficient damage at the end of the game.
What I find UGs really useful for is achieving EMs, since you can just leave one or two unexploded if you need an extra turn to line it up so that pulverizer gets the last hit. They even work as creature control (saved me more than once against Gemini by killing his momentumed spiders before he could TU spam them).
All the gods that use a reflective shield are relatively easy anyway, as long as you survive the initial rush. So destroyers won't have a hard time growing to big damage.
