Tips and tricks

Captain Cassie can be a good mid-game tower and for deal a horde of bloons.

When you got her at lvl 7 her moab takedown make her also medium for late game as she will help also in grouped bloons.

You're deciding which you will use, captain cassie or commander cassie? Captain Cassie is good at first 40 rounds of the game but Commander Cassie   at any round better for example she solos a normal moab with triple barrel only. The only weakness of Captain cassie is that she's weak at moab-class-bloons.

The privater works also with Warrior Bubblegum,  if you want to replace princess one with warrior is bad idea because you lose the regal presence.
