Fodder Ares?

As many already know, Ares' beautiful Dark Mysteltain allows him to do a lot of damage with AoE specials. BUT I had already decided (yesterday, in fact) that if any time I pulled an Ares I'd fodder him off to Myrrh. It turns out I just pulled a +atk Ares and now I'm all doubtful. I love my chip dealers and AoE specials, and I always use them. But I also love my tanks and always use them as well. What should I do?
