element specific works well. maybe the crumble can be other though.
while the name fits well with gravity, I think it's quite similar to charger. Is it possible to switch to an element without this type of beater?
Also 5 for a 7|5 creature is cheap. The crumble ability is an added bonus, not something that will most likely ever be used immediately.
I thought about making Crumble and "other" cost, but I don't remember why I didn't. Oh well, if I remember I will change it back. And now that I think about it, Gravity was a bad choice because I intended to make this of an element that didn't have any atk buffs, so that it would be more difficult to abuse its crumble. Maybe... Life? Not Water, not earth,(that has an excess of beaters already) Air wouldn't fit. I think it would only work in Aether or Time. Aether, because they have very little in way of beaters, and Time because it is literally an ancient golem attemting one last hurrah before crumbling into oblivion...
I don't really know, it would fill a gap in Aether which really lacks worthwhile creatures. But flavor accounted for, it should fit in Time.
I will ammend the original post with an untyped picture. Then I will post a poll for the viewers to vote on the element of this lug...
