Note - this build may take some practise to run well.

Thanks to Warden having a unique range of towers for crowd control, Coastal Bazaar starts to open up at a point before Infested makes it obsolete, and perhaps at a stage of the game where it threatens the norm of playing Dread Dungeon or Arcane Library instead.

Builder stats are on the side.

You will also need:
TB (1k)
Jester Upper/Wheeler (2k casting rate, 1k Wheel)
Adept builder with some ab1 (400 is fine)

Such stats are easily obtainable in Mythical armour with Fish in Bowls and Halloween Spooktacular 1 Weapons from Ruthless, which only needs 1k stats to clear.

First wave - build the Auras, buff beams and traps. Any leftover mana goes into the Mushroom and the Pylon.
Combat - be careful of the traps on the south core. The HP means they will need repair.

Second wave - add the Golem and the Warden towers. 

Combat - bring in the TB on a split, make sure to aim towards the South East or South West. I recommend a Stones Throw Spear from Volcanic Eruptiion as a minimum - the ricochet is useful.

Third wave - build the minions. You'll need to move them a bit for the Minions behind the forge, but overlord mode makes this easy.

Combat - add the Adept on a third split. Drop mana to them with the Jester and keep their ab1 active. That should manage the upgrades on all of the towers.
