When I look at my face-down Prize cards with Poipole's "Eye Opener" attack, do I have to put them back in the same order?
Yes, you only get to look at them, you don't get to rearrange them.

When using Blacephalon GX's "Burst GX" attack, does that count as "taking a Prize card" for the purposes of other attacks that do more damage "for each Prize card you/your opponent has taken"?
No, using Burst GX to put a prize card into the Discard Pile does not count as taking a prize card.

Does using Trumbeak's "Mountain Pass" Ability count as playing it from the hand? If so, would it be blocked if my opponent used Chimecho's "Bell of Silence" attack on the previous turn?
No, it is not being played from the hand. You are revealing the Trumbeak and then putting it into the Lost Zone; that is not blocked by Bell of Silence.

If you Knock Out a Pokemon using one of Tyranitar GX's attacks, do you get to take a prize card if the Pokemon is sent to the Lost Zone due to Tyranitar GX's "Lost Out" Ability?

What happens to any damage counters on Skiploom when it uses its "Floral Path to the Sky" Ability? Do they go on the Jumpluff that takes Skiploom's place?
Any damage counters on Skiploom are removed when it goes to the Lost Zone; they do not transfer to the Jumpluff that takes its place. Special conditions are not transferred to the new Jumpluff either.

What happens if I use Skiploom's "Floral Path to the Sky" Ability but fail to find a Jumpluff in my deck?
Skiploom stays in play, and since you searched your deck the ability is used up for the turn.
