This map has won against me more than I've won against it. I've tried so many different combinations of builds, and this is the only thing I've had decent success with. The tower stack was inspired by someone else, but I can't find their build to remix it.
The bulwark is nestled up next to the phys walls. Highly recommend phys wall EV. My EV Phys wall is 6.5k -- She gets all the gear that doesn't work for anyone else. Ogres as close to the bulwark as the game will let you, and the mages back a bit so that the Super Mario KO swing doesn't kill them.
The phys wall, hermit web, and reflect beam are all almost on top of each other, but make sure the reflect beam protects the wall and the hermit's web (not your tower setup, the boost monk will fix any snot that makes it through).
I sometimes edge the golem into lapsing over the edge of the physical wall, but recently tried and it worked okay with the bulwark (no golem overlap at site 4).
At my stats it requires two summoners with App/Hunt bombo (2/2) and a tower boost monk to go well.
