Abilities » Theta Stop
If Sceptile-EX has its Spirit Link tool attached, but Banette's "Tool Concealment" Ability is in play, what happens if you evolve to Mega Sceptile-EX with the "Theta Stop" Ancient Trait?
Theta Stop prevents the effect of Banette's ability against Mega Sceptile-EX in time for the Spirit Link tool to turn back on and not make you end your turn.

Does Golurk's "Double Type" ability which says "As long as this Pokemon is in play it is both {P} and {F} type" block Flareon's "Flare Effect" ability or Vaporeon's "Aqua Effect" ability or Jolteon's "Electric Effect" ability which adds {R} or {W} or {L} to any stage 1 Pokemon?
No. Golurk would have all 5 types if all of those Abilities were present.

If Flareon's "Flare Effect" ability or Vaporeon's "Aqua Effect" ability or Jolteon's "Electric Effect" ability adds Fire or Water or Electric type to a Darkness Type Pokemon, does Dangerous Energy get discarded since it says, "If this card is attached to anything other than a {D} Pokemon, discard this card"?
No, it is not discarded. Even with the addition of another type to the Darkness Pokemon it is still also a Darkness Pokemon.

Abilities » Bright Down | Attacks » Gastro Acid
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.

Abilities » Tool Concealment
Banette's "Tool Concealment" ability means Pokemon Tool cards simply have no effect. They are still considered as Items and Pokemon Tool cards, so "Garbotoxin" still works, "Startling Megaphone" would be able to remove them, etc.
