Imprison is the best move against a Ditto

Nice,but I play pokemon violet

OK but it will have imprison as well and if it has imposter it will have a chance that it's faster

what does imprison do already?

Prevents the target from using any moves that are known by the user

how do you get a creature that knows imprison and transform then?

Ditto learns the moves of the Pokemon it transforms into

btw quick claw can fix your speed problem

True, didn't think of that

You're welcome :)

yes but i thought it was to prevent ditto from transforming.
