Build wave: Make sure dsts are basically facing towards spawn besides the north and northeast one, just make sure the north is facing towards core and northeast faces the black line area.
MAKE SURE DSTS AND LT's ARE SEPERATE STACKS
Make sure to up the buff beam, i typically grab the spawn chest, build auras warp back then with ev grab the left chest by the web wall and build the beam and up to max.
When i swap to app I grab the right chest by the web wall so I have enough mana.
You have extra du left over cuz of the web walls, so if you accidentally place them 1 extra du or whatever it doesn't really matter.
Shrooms kinda optional you could just use another LT, i've found it speeds up the waves overall.
W23 Combat: Summoner (hunt + monk guards) <--- Place next to the lt's it helps chain the stuff on the north core + TB
W24: same shit just add splits after wave starts
p.s. if you get a ++ seahorse I will personally bomb your house :)
