x2Phantom Transformation
Once during your turn, you may choose a Stage 1 Pokémon, except any Zoroark, from your discard pile. If you do, discard this Pokémon and all attached cards, and put the chosen Pokémon in its place.
Night DazeIf it thinks humans are going to discover its den, Zoroark shows them visions that make them wander around in the woods.
On my last turn I attacked with Zebstrika's "Coordinated Bolt" attack. If Zebstrika gets KO'd or otherwise leaves play and on my next turn I use Zoroark's "Phantom Transformation" Ability to bring the Zebstrika back onto the Bench, can I use that Zebstrika's "Coordinated Bolt" attack with additional damage.
Yes, you can. Although Zebstrika left play and came back it is considered a different Pokemon on the previous turn.
If I use Zoroark's "Phantom Transformation" Ability to put a Stage 1 Pokemon from my discard pile in its place, may I evolve it into a Stage 2 Pokemon right away?
The Stage 1 Pokemon you're putting in play is completely new; nothing carries over, and you can't evolve a Stage 1 that came into play that turn.
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.
