Ok, for a while now I have been wanting a trainer card that would allow me to switch evolutions on the fly.... Discarding or returning the top evolution to your hand, and replacing it with another. Since most basics and stage 1's have multiple evos, this would be a fun combo. Stuff like Wobbeffett would live in fear of this card, being able to switch from an EX to a non EX. Well, this can be sorta done, but not quite to the same degree, its a 2-card combo as of now. Basic to stage 1's can use Retro Energy/Undersea Ruins and Rare candy or Wally's training, while Stage 1's-2's can use those plus Wally (Rare Candy only working when played on basics) Its not the best combo ever, and requires a little to pull off, but nifty none the less. This works great for Pokemon like Eevee with its Multiple Eevo's. It works well in decks where you have both the EX and the non EX in the deck, and a great counter for a Wobbuffett. An Eevee deck in the deck forum helped me see this combo, its kind of a cool idea, if you can fit it, or run a deck like one of these.
