If you use your U-turn and it KO the opponent's Pokemon, what happen if the Imposter Ditto switch in first?
Will it ability failed or will Imposter active after the other Pokemon is switch in?
Ditto's 'transformation' is delayed a turn, in this showdown battle, you can see that Lokix uses u- turn to knock out the Inkay, and then Lokix switches to ditto, Corviknight then replaces Inkay. Note that Ditto has to then use transform the next turn (2nd turn of the battle) to copy the Corviknight. Contrasting this second showdown battle, where you can see Ditto immediately copies Corviknight upon entering the field, thus saving two turns (you don't have to use transform to waste one turn).
