Place the stack on the northwest core such that the Wisp Den has visibility to wyverns flying outside.
Max both Buff Beams
Max Wisp Den and Pit Shroom on the northwest core
Upgrade auras in the northwest corner at least 3-4 times
Max Nature Pylon
Not all reflects are needed, arguably none, but at least one reflect on the west side helps against Ogres' projectiles.
Waves:
First wave: Upgrader + TB
Max all towers
TB stays near the Forest Golem and aims west (black arrow)
Ensure the TB does not die to Harbringers! I find it easier to survive if I glue the TB against the west side of the tree in the center of the map, centered or slightly a bit to the north.
Other waves until last: TB + (Warden builder or Summoner with two Huntress Guardians).
Last wave: TB + Summoner with two Huntress Guardians + Warden Builder + Wheeler
