The strategy in this stage is to focus the backliner enemies as much as possible before killing the Primeval Cyclone. LD units such as Medalist Cat, Golfer Cat, and Awakened Mina, along with Shockwave units like Manic Macho Legs and talented Pizza Cat can accomplish this task. Talented Rodeo Cat can easily help keep the Primeval Cyclone from destroying your LD stack. A general lineup may consist of 3 meatshields, Rodeo Cat, and 6 LD/Shockwave units. It may help to replace some of the LD/Shockwave units with long-ranged units in case the Primeval Cyclone dies before you can finish off the rest of the backliner enemies.
