Sudowoodo BKP Watch and Learn copying GX attack

[Chairman Kaga]

1. Can I use Sudowoodo's "Watch and Learn" to copy an opponent's GX attack used on their previous turn?
2. If yes, does this count as my GX attack for the game?
3. If yes, and I have already used my GX attack for the game, does the attack fail?

 

[PokePop]

1. As long as you have not already used a GX attack, yes.
2. Yes it would
3. Yes, the attack is valid to do, if you have the correct energy, but then the copy would fail.
