You win some, you win some more.

In addition to the guy who collects Warp Worlds, my LGS also has guys who collect Prodigal Sorcerers, Terminates, and Conquering Manticores.

The same guy who collected the Manticores and had me make this for him also happened to be collecting another crap rare from Rise of the Eldrazi: Splinter Twin. Yeah, that worked out well for him.
