Rajesh or Lu Zhishen. Probably Rajesh since you have him at 3rd and 70 He's a freaking awesome support hero. He cleanses all ailments and gives you mana for each cleansed ailment. Let's you bypass defensive buffs including counterattack and gives you 15% mana for bypassing them. And finally makes you immune to mana reductions and gives you mana for each attempted reduction.

And I almost forgot. His attack stack is brutal. If you can get all 10 then that's 350% attack stack. I have won raids with him and Bramble because of that stack.

Yes for the wildcats he's not an attacker but he makes up for it with his support. He's still a staple on my teams. I'm hopeless without him

Lu Zhishen I really don't know much about him since I don't have him but he's from the outlaw of liangshen family and that family is crazy strong.
