In my opinion, Mard Geer is powerful for a few things. Mard Geer possesses great speeds as to being able to dodge land destroying slashes by the Celestial Spirit King. Being able to break free of the petrification after a short time the CSK used to try and hold him. Being able use little effort against Sting and Rogue and receiving no damage what so ever. Being able to hold his own with Natsu + Sting and Rogue later on. Being able to still fight after receiving damage from Gray's Ice Devil Slaying Magic. Survived A brutal barrage of attacks from DF Natsu and still went on the offensive. And all this while he was second to E.N.D. As for the Memento Mori thing, that was pretty logical how that went down with how Gray used his Ice Devil Slayer magic.
