Abilities » Lost Link
Can Mew's "Lost Link" Poke-BODY use the attack of one half of a LEGEND Pokemon if its card is in the Lost Zone? Or what if both halves of the LEGEND Pokemon are in the Lost Zone?
No, you cannot. If a LEGEND Pokemon's cards are not in play, you cannot reference its attacks, Poke-POWER, Poke-BODY, etc.

Abilities » Catastrophe
If I use an attack that Knocks Out a defending Gengar with the "Castastrophe" Poke-BODY, but it also knocks itself out, does the attacking Pokemon go to the Lost Zone, or is "Catastrophe" no longer in effect when Gengar is KO'd?
Since both Pokemon are KO'd at the same time, Gengar's Catastrophe Poke-BODY is still working at the point when Knock Outs are evaluated. So the attacking Pokemon would go to the Lost Zone.

Abilities » Catastrophe
If my Active Pokemon does an attack that Knocks Out an opponent's Pokemon, but also switches my Active Pokemon to the Bench, would the Knocked Out Pokemon go to the Lost Zone if I bring up Gengar with the "Castastrophe" Poke-BODY?
Yes. Gengar is active at the end of the attack when Knock Out conditions are evaluated.

Abilities » Energy Signal | Energy » Rainbow Energy
What happens if I attach a Rainbow Energy to Roserade with the "Energy Signal" Poke-POWER? Do I get to use both effects?
If the Energy card you attached provides all types (for example, Rainbow Energy), then both effects would trigger. Energy Signal would both Confuse and Poison the Defending Pokemon.

When I use Smeargle's "Portrait" Poke-POWER to look at my opponent's hand, can I terminate the power's effect without choosing a Supporter card?
No, you cannot. You must choose a Supporter card when you use the effect if the opponent has one in their hand.

Abilities » Mischievous Trick
Can I use Rotom's "Mischievous Trick" Poke-POWER when I have no cards in my deck, to put a Prize card into my deck?
No, you can't. That would be far too mischievous.

Abilities » Mischievous Trick

Abilities » Opponent's Choice
When using Slowking's "Opponent's Choice" Poke-POWER, do you have to show your opponent what the cards are since it says 'you may reveal the top 2 cards'?
Of course you have to show the opponent what the cards are. The "you may" refers to using the power, not to being able to use it without showing them the cards.

Abilities » Portrait
Can I use Smeargle's "Portrait" Poke-POWER if I have already used a Supporter this turn?
Yes, you are not playing a second Supporter, you are just using the Supporter's effect as the effect of the power.
