Say I played Mimikyu V and used its "Dummy Doll" Ability on my turn. Then on my opponent's next turn, they play a Path to the Peak stadium. Does that cancel the effect of "Dummy Doll"?
Since the Dummy Doll Ability activated and placed an effect before Path to the Peak came into play, its effect remains.

Can I use Urn of Vitality to shuffle the card Impact Energy from my discard pile into my deck?
No, you cannot. Urn of Vitality is only able to target a specific card named "Single Strike Energy". Although Impact Energy is a "Single Strike" Energy card, it is not "Single Strike Energy".

When using Peonia, do I have to randomize my Prize cards after putting them back?
Rearranging the prize cards is not part of Peonia's effect, so wherever you put the new prize card is where it should stay until some other action causes the prize cards to be rearranged.

Can I play Peonia if there are no other cards in my hand?
Sure. In that case, you still put up to three Prize cards into your hand and then put them back down.

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.
