Delta Species was a set released a while back, but in some of the newer sets, they still release Delta Species related cards. Basically, Delta Species Pokemon are Pokemon with different types. Like Feraligatr Delta Species is an Electric type, instead of Water type. Ninetales is a Psychic type, instead of Fire type, and so on.
