Use buff beam trick by building buff beam to connect hint 1's auras upgrade to lvl 3, (4 if needed) upgrade the buff beam for app towers to 3, (4 if needed) then delete original buff beam.
I use upgrade Jester first wave (20th) upgrade as much as I can. Then bring in 2 Guardian Summoners (App/Huntress) and an Upgrade Summoner (Genie + Monkey) to upgrade the rest. Then Goblin Cupid + Crystal Core, I stop at wave 30 start.
PS. I would look into an flash heal macro for your summoner(s) as it makes the map more afk-able
PSS. Any pet works on your main summoner. I use GC because Copters sometimes shoot through reflects and it will heal your summoners as well as dps the Copters and DJinns
Hint 1: Electric and Ensare aura
Hint 2: Strength Drain aura
Hint 3: Move the gas trap closer to South core with Tower Move Jester
Hint 4: Trap Placement for East and West Cores
