Have Dwarven Defender full arua. Evolve Water Juggernaut with first attack as attack and heal self. Have the highest defense and HP for water juggernaut. Fire treant also have highest defense and HP with crit 100%. Speed doesn't matter here. Last creature is up to you. In this team everytime Water Juggernaut counterattacks it heals itself more damage then the other team and can deal so he pretty much becomes unkillable. His second ability will block revive on an enemy and eventually your avatar will kill them with his aoe attack. Very powerful team. Fire treant makes sure water juggernaut's health stays above 70% making sure that he reflects negative debuffs.
