Probably just my personal bias but I'll just reitirate why I found Mard Geer underwhelming, after typing a load of nonsense so anime only guys don't see the spoiler in the wiki activity page.

Mard's initial curse is the thorn curse .____. Ok, that's the most underwhelming curse out of all of them. Second one was Alegria, that was cool, but one can't help but think that if not for the Plutogrim it wouldn't have worked, as well as that for some reason it didn't affect Lucy. .___. wut? And there's little to suggest Horologium had something to do with that in the manga. His final curse was Memento Mori, something designed to make an individual cease to exist, neither dead nor alive. .___. Zero called, he wants his spell back. And not to mention, it got nurfed by Gray .___. If Gray managed to nurf that, what chance did it have to work on Zeref?

So it's because of these factors that I'm biased against Mard Geer. Is he powerful, looking back on it, yeah he is. Do I think he's up there with Hades, the four gods and the spriggan 12? Nuh. :/
