If I use Tauros' "Destructive Horn" attack, flip heads, and discard the only {M} Energy attached to my opponent's Orthworm ex, does my Tauros take damage from the Orthworm ex's "Pummeling Payback" Ability or not?
Since there are no {M} Energy attached when the effect of Pummeling Payback is triggered, no damage counters are placed on Tauros.

How much damage does Diancie's "Diffuse Reflection" attack do if I also have an evolved Pokemon with a Reversal Energy providing three energy?
The damage is calculated based on the number of Special Energy CARDS, not the amount of energy the card provides. So in your example it would only do +40 damage for Reversal Energy, not +120.

If Ting-Lu attacks with "Ground Crasher" against a 30 HP Cleffa with Bravery Charm attached while Jamming Tower is in play, would it do the damage first and KO Cleffa, or would Jamming Tower be discarded first and Cleffa survives due to its Bravery Charm reactivating?
The damage is indeed done first and then Jamming Tower is discarded, but lucky for Cleffa the check for KO does not happen until all damage and effects have been resolved. Cleffa would have 80HP and is not KO'd by Ground Crasher.

If an effect prevents Sinistcha ex's "Re-Brew" attack from placing damage counters onto the target Pokemon, do I still shuffle the Basic {G} Energy cards into my deck?
No, if you don't place any damage counters, you don't shuffle the Energy into your deck.

If I discard a Double Turbo Energy when using Greninja ex's "Mirage Barrier" attack, does it do 120 damage or 100 damage to two of my opponent's Pokemon?
You do 100 damage to the two. You first CHOOSE the energy you're going to discard, then do the damage (which is reduced for Double Turbo), and THEN discard the energy.

If Pokemon League Headquarters stadium is in play, how many energy are needed for energyless attacks like Cleffa's "Grasping Draw" attack?
Any attacks that normally cost no energy now require at least one energy to be attached when Pokemon League Headquarters is in play. However, if an effect like Cramorant's "Lost Provisions" Ability sets an attack's cost to zero energy, Pokemon League Headquarters does not add an additional energy requirement to it.

If I use Rabsca's "Revival Blessing" attack to put Charizard ex onto my Bench, can I use the "Infernal Reign" Ability to search for and attach up to 3 Basic {R} energy?
No you cannot, because Charizard ex is not being played from your hand to evolve 1 of your Pokemon.

If Iron Hands ex with Heavy Baton is KO'd by Quaquaval ex's "Exciting Dance" attack which pushes it to the Bench after doing damage, does Heavy Baton move energies attached to Iron Hands ex since it is on the bench by the time KO's are checked?
Yes. Heavy Baton checks for two things here: Iron Hands ex was damaged by an attack while it was your Active Pokemon, and Iron Hands ex was Knocked Out by that attack. So even though you don't check for a KO until the attack is completed, the criteria for using Heavy Baton has been met, so it can be used. This holds true for any similar Ability that triggers when the Pokemon is Active and gets damaged by an attack.

If Radiant Jirachi with the "Entrusted Wishes" Ability is KO'd by Quaquaval ex's "Exciting Dance" attack which pushes it to the Bench after doing damage, do you still get to search your deck for up to 3 cards or not since Radiant Jirachi is on the bench by the time KO's are checked?
Yes. Entrusted Wishes checks for two things here: Radiant Jirachi was damaged by an attack while it was your Active Pokemon, and Radiant Jirachi was Knocked Out by that attack. So even though you don't check for a KO until the attack is completed, the criteria for using Entrusted Wishes has been met, so it can be used. This holds true for any similar Ability that triggers when the Pokemon is Active and gets damaged by an attack.

Can I place 9 damage counters on Walking Wake using its "Undulating Slice" attack if it would result in enough damage to knock itself out?
Yes, you can put up to 9 damage counters on Walking Wake even if it doesn't have that much HP remaining. Undulating Slice will do 20x each damage counter that was placed, and at the end of the attack Walking Wake will be knocked out.
