I made something very similar to this, but I also used Gravity Mark, Aether Pendulums, Electrocutors, and Twin Universes. That way, if my opponent had a nice big creature, too. I'd just copy it, then Chimera to make it even bigger. Also, I'm not sure if it still works now, but if you lobo'd a Chimera, you could TU it without them killing each other. Sure, it lost momentum, but it was still pretty damn big...and if you played another Chimera, it'd be twice the size of the first.
