This is a Hybrid-Cloud pet build, meaning we built specifically around the setup as discussed below. It cooks much faster than my normal PS build. We did need to cycle HB about mid wave, but TB could stay on all the way through.
Party:
1 Hybrid Monk (Tower Boost and Hero Boost stat as high as you can get them)
2 Hunters with cloud pets (auto firing, one facing NorthEast, one facing NorthWest)
1 Summoner with cat/huntress pets (cat boosts the DPS and Huntress boosts the towers)
