The secret spice of this list is running a very small PK engine with Rusty to put up two Fog Blades negates. The trade-off is you lose 2 Apollousa negates, but with the amount of monster negates running around, losing this doesn't really matter (besides, a two mat Apollousa isn't that great anyway)
The new line is to use Elpy and Pisty to make Dillingerous dragon, then use Dill and the monster summoned off Pisty (or whatever other monster you have, but try to keep Rokket Tracer alive otherwise you can't make Savage) to make Rusty. This gets Dill into the graveyard which can then be resurrected to make Verte Anaconda off Rokket Tracer's effect.
