Like a ground type giving it to a flying or dragon giving it a fairy

Switcheroo has limited useage and is limited to fairly novelty-like Pokemon. Moreover, its kind of gimmicky and frankly, if your Pokemon doesn't have the coverage to take on certain types, you shouldn't be using it.

Not trying to sound rude, I appreciate the input.    I'm just looking for a truly viable option. Rep given!
