At first glance this fight didn’t seem too hard, but I found out differently when I started to try to throw teams at him.
Synopsis: You can’t let Carpe Diem live too long, else he’ll Dreadful Breath your whole team into oblivion. Spirus hits really hard with his Arcane Blast, and as usual, being faster than your opponent is key.
Goal: To defeat the tamer with 2 pets so that Elekk Plushie can be carried through the fight.
Wise Mari’s Team
Carpe Diem with Grasp, Cleansing Rain, and 
Dreadful Breath
Spirus with Arcane Blast, Healing Rain, and Soul Ward
River with Whirlpool, Pump, and Dive
Your Team
Tiny Flamefly – Alpha Strike, 
Hiss, 
Swarm
Lil’ Bling – Inflation, Blingtron Gift Package, Make it Rain
Elekk Plushie
Your tiny Flamefly will easily take care of Carpe Diem with a Swarm and two Alpha Strikes. You’ll then need to immediately swap to Lil’ Bling to deal with Spirus. When Spirus uses Soul Ward, use the Blingtron gift Package to heal yourself up at any time. Use Make it Rain and then use Inflation for continued damage. It might be close, but Lil’ Bling will finish off Spirus. The last part of the fight involves setting up your Tiny Flamefly to finish River. If Gift Package and Make it Rain are both on cooldown when River enters the fight, just pass a turn and then use Make it Rain. You’ll most likely die at this point. If neither are on cooldown, start with Make it Rain. Use the Gift Package (which will heal you because River’s underground), and then use inflation. When you bring your Tiny Flamefly back in, make sure you are the fastest pet in the fight. If you aren’t, use Hiss. Constantly Alpha Strike-ing will finish off River.
