In the future, it's very likely these will hold great value and also be a solid addition to anyone's collection!
The ability to sacrifice an earthbent land makes the first mode ok enough that I think this card works out to being good enough
Craterhoof Behemoth is shown with ghostfire tusks and horns, helping to give a mystical element to the massive Beast
I think that this card is great for utility in decks such as Neyith of the Dire Hunt and Grothama, All-Devouring that care about fighting, but I also consider this an amazing top-down design from a flavor perspective
Any card that pushes combat and interaction is a good card in my book
The flexibility to not only copy your own spells but opposing spells as well means you should always find a good target, whether it be removal, card draw, or anything else
