Trickster

The  is a Tier 5 Tank that upgrades from Mailman and Engineer at level 60.

Design
The has similar barrels to Mailman, but its tapering barrel at the end is pushed outward and connected to its base by a thinner barrel, resembling the thin barrel of Engineer and giving the whole tank a similar barrel layout to Spawner.

Technical
The is pretty much just a combination of its pre-evolutions. It produces Engineer pillboxes with turrets on them that explode into 4 traps once they expire, like Mailman's blocks.
