Star Reef - 2

Strategy
Warning #1: Be careful! Poltergeist and Zombie Knight can lower your attack power and Stinky Zombie can provide poison to you! If the Rage Chili is full, give it to Matilda so she can cleanse these harmful effects!

Warning #2: Don't use the Rage Chili on wave 1. Use it for Matilda at wave 2 (once only) and for The Blues on wave 3 at the first time it is full. At the later times, use the Rage Chili for Matilda if the birds' healths are under 70% and if otherwise, use it continue for The Blues on wave 3 (unlimited).

Choose Matilda in Druid, Bomb in Cannoneer and The Blues in Rogues. In every waves, attack every turn with Bomb, then, heal with Matilda if the birds' health is not full, otherwise, attack with her. If Poltergeist, Stinky Zombie(except wave 3) or Frankenpig is about to attack, protect with The Blues on the bird that have the highest current health. Repeat this over and over until you win or lose.
