I've never seen anything remotely like this next idea, so I don't know how it will perform. I think I'll actually try this out in pvp1/2 and see how it goes. When trashduke mentioned chimera it came to mind somehow, because I was trying to imagine what use it would be.

Armagios to absorb damage in the early game, dragons to provide it later, both of which are extremely hard to kill. Opponent will probably race damage slightly faster, since those creatures are more focused on hp. Then.... suddenly an enormously fat chimera with like 100hp that absorbs a ton of creature damage while still dishing it out. Even at 15 quanta it might be a little light, though; I'm not sure. Also, 100% pure monogravity ftw.
