This build was adapted from Rumple's and tested with 6k main stat heroes. It is made to be as safe as possible especially when your tower boost goes down.

Build Note 1: I tried using mortars like in Rumple's build but I found the mortars kept knocking djinn into the spawn areas where they would get stuck.
Build Note 2: I did not find that I needed minions with this setup and properly managed TB. Add minions if needed.

Wave Note 1: I stop tower boost at mob count 1800 and then start the tower boost after cool down to handle the final Genie/Sharken rush.
Wave Note 2: I used a tower boost monk, two Summoners with Apprentice and Huntress Guardians, and a Summoner with two Squire Guardians. This last hero could be whatever you wanted like a Jester for gold wheelings. I had hoped to keep the Warden builder in, but during they died every wave when the TB would go down. I ended up using a double Squire Guardian Summoner as I find when you are doing this on the low stats side, the added HP does help you out. With higher stats, we have alot more options.
