I can't for the life of my figure out me third pet for my team.
Mana Wyrmling(Main pet, not switching)
Spells: Flurry, Amplify, Mana Surge
Spells: Poison Lash, Soothing Mist, Stun Seed
I call it my Mana Cannon team. Generally I open with Lasher and go Lash > Seed > Mist > Swap Wyrmling(seed damages and stuns) > Amplify > Mana Surge.
all I can think for my third pet would be a self healing pet like Restless Shadeling or something, incase the enemy team is strong against my cannon. Or another family of pet similar to my Wyrmling, who I can swap to under the powers of my Lasher to blow them up.
