This map should be named 'Steve's temple abuse', or perhaps 'Steve's love for hounds', because those are the two options you've got. You can get just one of each creature type, but you get them immediately. So as soon as you get a temple you can keep sacrificing insects for as many warlocks/biles/mistresses as you want, or go for horned reapers instead. When you build a scavenger room you will get countless hell hounds, the only unit there's lots of in the pool. You basically fill up immediately to 100 units if you don't quickly sell your scavenger. There's a lava lake, and below there's quite a bit of heroes, which are the only enemy units on the map. Either build up a strong army (there's gems and all the time in the world) or let the heroes up in smaller parties by building and selling the bridge for a very easy victory.
