If I use Zoroark's "Phantom Transformation" Ability to put a Stage 1 Pokemon from my discard pile in its place, what happens to any damage counters or Special Conditions or effects that were on the Zoroark?
The damage counters and any Special Conditions and any effects will be removed from the newly swapped in Pokemon.
