Top 5-
1.The Battlehammer blast radius is huge so don't get too close to it.
2.Weavile is also good in small and big places in big places battlehammer won't do recoil damage in small places your opponent will get trapped.
3.If your half turret goes down below 50 health bring it back it's hurting you more than it's hurting others.
4.Set the half turret next to some life and out of the way so no one will see it when they try to get health then when they are weak the turret kills them.
5.Recommended arena:Incubation Vault
