It feels too much like shoehorning two land types together, and not for any reason since they don't work together in any meaningful way.EDIT: This next card is also a land, and is exceedingly simple... but also makes no sense in any Limited environment whatsoever, though it should be fine in Eternal ones:
Land - Desert Gate ... Uncommon
T: add C
And it would make sense in limited, as it would be printed in a limited environment where those types mattered.
