If I have Milotic with "Dew Guard" Ability in play, what happens if my opponent plays Riley?
Your opponent reveals the top 5 cards of their deck but you would not choose 2 cards, and they get to put all 5 cards into their hand.

What happens if a Pokemon with Splash Energy attached is Knocked Out by an attack while Lost City stadium is in play?
The order of resolution for the effects can be decided by the owner of the Pokemon with Splash Energy attached to it. So the Pokemon can either go to the Lost Zone and stay there, or use Splash Energy to return the Pokemon to your hand.

If I have 5 cards in my Lost Zone and my opponent has 5 cards in their Lost Zone, can I use Sableye's "Lost Mine" or Giratina VSTAR's "Star Requiem" attack or Fantina?
No. Each player has a separate Lost Zone above their Prize Cards that they put cards into. You yourself must have 10 cards in your Lost Zone in order to do either of those attacks or to play Fantina.

If my opponent KO'd one of my Pokemon and then on my next turn I use Origin Forme Dialga VSTAR's "Star Chronos" attack, or if I KO one of my opponent's Pokemon with Medicham V's "Yoga Loop" attack, can I play Raihan on the second of my two turns from either of those attacks?
Yes, you can. Your Pokemon was KO'd "during your opponent's last turn" regardless of how many turns you take since then.
