I guess it's good mana-fixing if you're on some crazy 4-5 color deck, but there are better options
They are custom made by me and are not going to be exact replicas, although I try to get them as close to the real cards as possible
While Shadrix doesnt fit the criteria for group hug or pillow fort specifically, its got the added benefit of being a 2/5 with flying and double strike thatll sit as a threatening rattlesnake on your board while you assemble your Sanguine Bond combo

The Blastoise ex Special Art Rare is a solid card to get graded if youre lucky enough to have pulled it
