Hi, 

I am currently running my first build for 2key brutal with deacon, artak, kael, war maiden and gravechill killer.

I am planning to move to nm and unm cb. I am thinking of the below build. Please advice

Sandlashed Survivor(Defence Lead) -  Ally protect  and buff extender by 1 turn

Artak- HP burn and Atk down

Kael- Poisoner

Heiress- Increase spd and counterattack

Mauoleum mage- Increase def, remove debuffs

Please advice if this build looks feasible as I dont have any unkillable team or champs like demytha,maneater, pain keeeper, skullcrusher etc

Thanks
