With Florges' "Flower Picking" Ability, can I use it when my opponent only has one card in their hand? Or can I use it to shuffle in only one card instead of two if my opponent has two or more cards?
If the opponent only has one card in their hand you do as much as you can, so they reveal & shuffle in the one card. But if your opponent has two or more cards in their hand you must choose two of them, not just one.

Let's say I have two copies of Garchomp & Giratina GX in play, and one of them has a Double Dragon Energy and a basic Psychic Energy card attached to it. If I play Tag Switch, am I able to select only one of the Energy being provided by Double Dragon Energy, so that I may also move the Psychic Energy too? Or if I had two Double Dragon Energy cards attached, could I pick one Energy from each Double Dragon Energy for Tag Switch and move both cards?
Yes, you can either select 1 Energy from each Double Dragon Energy to move both cards, or you could select 2 Energy from one Double Dragon Energy to move just one card.

Can I use Sabrina's Suggestion to copy an opponent's Green's Exploration in their hand if I have a Pokemon in play with Abilities?
Nope sorry, you still have to obey the restrictions on the copied Trainer card. Since you have a Pokemon with Abilities in play you cannot use Green's Exploration even from your opponent's hand.

If my opponent used Latios GX's "Clear Vision GX" attack on me, could I use Bonnie to allow my Zygarde-GX to use its GX attack?
No, you cannot. Although Bonnie would normally let Zygarde-GX re-use its GX attack, the effect of Clear Vision GX is on Zygarde-GX and that still prevents using *ANY* GX attacks.

If my opponent has used Latios GX's "Clear Vision GX" attack, would my Keldeo GX be able to use its "Resolute Blade GX" attack?
Yes. The effect of Clear Vision GX is placed on each of the opponent's Pokemon, and since Keldeo GX's Pure Heart Ability prevents all effects of attacks done to it by your opponent's Pokemon GX, it is unaffected by Clear Vision GX.

If my opponent has used Latios GX's "Clear Vision GX" attack, do I get to draw 7 cards if I use Hala?
If you already used your GX Attack before Clear Vision GX, then yes you get to draw 7 cards for Hala. Otherwise no, getting hit by Clear Vision GX doesn't mean you have used your GX attack for the game.
