If my opponent has no deck and I use Luvdisc's "Heart Wink" attack and flip heads on my turn, does my opponent lose or does the game continue?
Regardless of whether Luvdisc's attack permits them to draw or not, if a player has no card to draw at the start of their turn they lose the game.

Arbok's "Gastro Acid" attack says the Defending Pokemon has no Abilities until end of your next turn. Is that referring to the opponent's next turn or the attacking player's next turn?
It refers to the end of the next turn of the player who used Arbok's attack.

Can you use Devolution Spray or Golurk's "Devolution Punch" attack against a Mega Pokemon, and if so what happens to the Mega Pokemon?
Mega Pokemon are evolved Pokemon, so the Mega Pokemon card is removed, but the underlying Pokemon and all other cards attached stay in play (unless the Pokemon is KO'd, of course).

Is Rock-Paper-Scissors played by pumping my arm 2 times then throwing my choice, or pumping 3 times then throw?
According to the current "Play! Pokemon TCG Tournament Rules and Formats" document, the procedure is a three-count priming and then the simultaneous throw of the choice, for example, "Rock-Paper-Scissors-Shoot" with the choice thrown on "shoot".

Ninjask's "Night Slash" attack has an effect where it may switch with a Benched Pokemon. If it switches, would the Defending Pokemon's Rock Guard effect take place on Ninjask or on the new Pokemon?
Rock Guard references putting counters on "the Attacking Pokemon", so Ninjask would still take the damage counters even if it goes to the Bench.

What happens to the opponent's Energy if I use Krookodile's "Piston Headbutt" attack, but my opponent's Pokemon has Silver Mirror attached to it?
If Silver Mirror is attached to the Defending Pokemon and it is not a Pokemon-EX you cannot move an Energy off of it. If the Defending Pokemon does not have Silver Mirror attached, a Benched non-EX Pokemon with Silver Mirror is a valid target for the choice of where to move the Energy to, but since Silver Mirror prevents all effects of attacks done by Team Plasma Pokemon the Energy would be discarded rather than attached to the Benched Pokemon.

Say you have Silver Mirror attached to one of your non-EX Pokemon, and it is the only remaining Pokemon. If your opponent's Beheeyem tries to attack with "Damakinesis", the six damage counters obviously don't get moved to the Pokemon with Silver Mirror since Beheeyem is a Team Plasma Pokemon; but do the damage counters get removed and then discarded, or do they not move at all?
The non-EX Pokemon with Silver Mirror attached is a valid target for the choice of where to move the damage counters to, but since Silver Mirror prevents all effects of attacks done by Team Plasma Pokemon the damage counters would be discarded rather than attached to the Defending Pokemon.

For Cradily's "Lifesplosion" attack, do I need to have the corresponding Stage 1 Pokemon in play in order to put the Stage 2 Pokemon on my bench?
No, the Stage 2 Pokemon card goes directly onto the bench, even though it does not count as a "Basic Pokemon".
