I guess I'll try to make a good Battle level if I am able to. I suggest putting The Temple of Suffering and An Uninspired Psych Level in at least. There weren't many good Battle levels created this/previous month, and the older ones are played a bit. Maybe other levels that could be in:

Green Hill Citadel(or whatever it was called.. Blur's BoredSet level)
XLM Woods Far East
Night of Diamonds

That's all I can think of..
