Can I play Peonia if there are no other cards in my hand?

Can I play Flannery if my opponent only has a Special Energy in play but no Stadium, or vice versa?
Yes, you can play Flannery as long as there's at least 1 thing to discard. However, it's not optional, so you must discard a Special Energy and a Stadium if both are in play.

If Path to the Peak is in play, can I use Liepard V's "Hidden Claw" Ability when I play it from my hand onto my Bench?
No, Liepard V is considered in play by the time Hidden Claw activates, so it won't work due to Path to the Peak.

If Kecleon has no Energy attached and I attach a Psychic Energy to it when Old Cemetery is in play, will Kecleon's "Chromashift" Ability kick in before checking for Old Cemetery or will Kecleon get 2 damage counters?
Old Cemetery's effect will happen first, so Kecleon will receive 2 damage counters.

If my opponent uses Guzzlord's "Red Banquet" attack and my Active Pokemon with Big Parasol attached gets KO'd, does my opponent get to take an extra prize for "Red Banquet" or not?
Big Parasol prevents all effects of attacks from your opponent's Pokemon done to your Pokemon; but taking an extra prize is a game effect, not "an effect done to your Pokemon", so your opponent gets to take the extra prize.

Say Team Magma's Secret Base and Mimikyu with "Shadow Box" Ability are both in play. If I put Dedenne GX on the Bench, can I use its "Dedechange" Ability or will it be blocked because it has damage counters on it?
Since Dedechange and Team Magma's Secret Base are simultaneous effects, it is up to the player to choose the order in which they will be applied.

When I play Cheryl, can I choose not to heal one of my Pokemon that only has a few damage counters on it so I can avoid discarding the Energy attached to it?
No, there is no choice. All of your Evolution Pokemon that have any damage counters on them will be healed and have to discard their energy when you play Cheryl.
