If I use Mega Sceptile EX's "Jagged Saber" attack against Giratina EX with the "Renegade Pulse" Ancient Trait, does Mega Sceptile EX's "Theta Stop" Ancient Trait prevent "Renegade Pulse" from blocking the damage? If not, then does "Renegade Pulse" prevent "Jagged Saber" from attaching any Grass Energy?
Renegade Pulse prevents all effects of attacks done to Giratina EX, but it does not "do anything" to Mega Sceptile EX for its Theta Stop to kick in. So the damage part is blocked by Renegade Pulse, but the effect of attaching energy is not being done to Giratina EX so that part of the attack does not get blocked.

Does Golurk's "Superpower" attack apply Resistance to the +20 damage it does to itself?
Yes, as long as Golurk is Fighting Type at the time of the attack, Resistance would be applied.

Can I use Close Encounter after my first turn, or only during my very first turn of the game?
You can use it on any turn, including your turn if you go first (when you normally would not be allowed to attack).

Both players have 1 prize left. Player-A uses Jirachi's "Doom Desire" attack. Player-B attacks Jirachi with enough damage to KO it with the same Pokemon that got hit by "Doom Desire". Who wins? Or is it a tie?
The KO from Player-B's attack happens before the end of his turn, so the game is over before Doom Desire's effect gets to happen. Player-B wins.

If my opponent used Banette's "Evolution Jammer" attack, can I use a Pokemon with the "Delta Evolution" Ancient Trait to evolve anyway?
No, Delta Evolution does not override Evolution Jammer.

What happens with the "Homing Pidove" attack if I choose not to shuffle my deck?
Homing Pidove tells you to look at the top card of your deck. You don't get to keep that card, so you put it back onto the top of your deck. Then you can choose whether to shuffle your deck or leave it the way it is.

My active Arbok uses its "Gastro Acid" attack against Weezing with the "Aftermath" Ability. Then on my opponent's turn he uses Weezing's "Smogbank" attack to do 20 damage to each of my Pokemon. If I have Latias-EX with the "Bright Down" Ability on my bench, would it take damage or not?
Since Weezing has no Abilities due to Arbok's attack, it would do 20 damage to Latias-EX.

Pachirisu's "Trick Sticker" attack says, "the Defending Pokemon's Weakness is now {L} until the end of your next turn". Does that mean the weakness is applied "now" before the damage is done for this attack?
Nice try, but no. Like all attacks that don't explicitly say otherwise, the effects of attacks are not applied until after damage is done.

Say the "Sky Field" stadium is in play and I have 8 Pokemon on my Bench. My opponent uses Salamence's "Shatter" attack to KO my Active Pokemon and discard the stadium. Do I promote one of my Benched Pokemon first, or do I reduce my bench size to 5 Pokemon before promoting?
When the Sky Field stadium is discarded during the attack, the bench size is reduced immediately before going any farther. So after promoting your new Active Pokemon there will be 4 Pokemon on your Bench.
