If Barbaracle with "Lost Block" Ability gets knocked out, do the opponent's Prize cards go into their hand or into the Lost Zone?
When Barbaracle is KO'd it goes to the discard pile; Lost Block is no longer in effect, so your opponent gets to take the Prize card.

Can I use Comfey's "Flower Selecting" Ability or Colress's Experiment if I have only 1 card left in my deck?
You can play either of them with only one card left in your deck; but you have to put the card into your hand, you cannot discard it or put it into the Lost Zone.

If my opponent has an Empoleon V with "Emperor's Eyes" Ability active, and I have both an Eevee with a Memory Capsule attached and an Eevee with the "Resonant Evolution" Ability in play, if I evolve the Eevee with a Memory Capsule into a Jolteon with "Thunderous Awakening" Ability can I use "Resonant Evolution" or not?
Yes, that will work because Emperor's Eyes has been disabled.

Does a poisoned Fusion Strike Pokemon with Fusion Strike Energy attached take additional damage counters from Radiant Hisuian Sneasler's "Poison Peak" Ability?

If I have Comfey in play and I use its "Flower Selecting" Ability, can I then use Thorton to switch it with a different Comfey and use "Flower Selecting" from the new Comfey?
No, that won't work. Even though the new Comfey is a different Pokemon than the first one, it remembers the Flower Selecting Ability was already used this turn so you cannot use it again on that Pokemon.

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.

When putting Banette into the Lost Zone with its "Puppet Offering" Ability, do you also put the underlying Shuppet card into the Lost Zone too?
