Question

I know that you get the Ex points from What ever Ditto transforms into (Having it transform into blissey gives HUGE points) but What about EV's? Do I get Ditto's EV's or the pokemon it transformed into (Does having it transform into a crobat an ddefeating it give me super fast speed)

Answer 1

"Transform changes the user's current type(s), current stats, current stat levels, current move(s), current species, current cry, and current catch rate to that of the target's."

Ditto gives off one HP EV, but when he transforms, he still keeps his own yield, meaning he still gives off the same one HP EV when he is transformed into another pokemon.
