Yes and no, but honestly his second and third skill is what done him in.

Say the enemy team has the gimmick to keep landing critical hits and if they have a class that counter this particular servant plus inflicting numerous debuffs that can bypass his resistance rending those passive skill null and void which in turn backfire on him if he ever attempt to use the second or third skill.

At best, he will serve as a support and DPS making him a hybrid and at worse, just getting your team wasted given how the enemy most likely have no cooldown duration ever in-game. They can spam their skills after all unlike our servants who has a CW duration due to game mechanics being a bitch.
