I chose the following:
Voodoo Figurine (Undead/Dragonkin/Elemental)
Wind Rider Cub (Beast/Flying/Critter)
Ethereal Soul-Trader (Humanoid/Magic)
I tried to be all well-rounded as I could with only having 3 available. The only teams I have a hard time beating are two AoE healers and a DPS or if the opposing team is way way higher than me.
What's your team?
