If Aegislash with the "Durable Blade" Ability is Knocked Out by damage from my opponent's attack, do I put its underlying Doublade and/or Honedge cards into my hand or into the Discard Pile?
You put all the Pokemon in the evolution line into your hand. Any other cards attached such as Tools or Energy are discarded.

If I try to use Munchlax's "Snack Search" Ability and flip Tails, is my turn still over?
Yes, it is. Even if you don't flip Heads, the Ability is still considered "used".

If Reshiram & Charizard GX has the extra 3 Fire Energy for "Double Blaze GX's" bonus effect and attacks a Whimsicott GX with "Fluffy Cotton" Ability, does the Whimsicott GX get to flip for "Fluffy Cotton" or does the "Double Blaze GX" attack go through automatically?
Technically speaking you still flip for Fluffy Cotton, but regardless of the flip's outcome the Double Blaze GX attack ignores the effect and does the damage anyway.

If I use Raichu's "Evoshock" Ability to paralyze my opponent's Active Pokemon, does the Paralyzed status condition get removed if my opponent attaches a Stealthy Hood to that Pokemon on their next turn?
The Evoshock Ability's effect is to Paralyze the opponent's Pokemon; once that Special Condition has been placed it is no longer considered an effect of the Ability at the time your opponent attaches the Stealthy Hood. Therefore, your opponent's Pokemon remains Paralyzed.

Can you play Darkrai GX with "Restoration" Ability from your Discard Pile if Power Plant is in play? And if so, do you do all of its effects?
Since the Discard Pile is not considered "in play", Darkrai GX can use its Restoration Ability to put it onto the Bench and attach a Darkness Energy card from the Discard Pile to it. Once all of the Ability's effects are complete, then Power Plant shuts off the Ability.

If I have Porygon-Z with "Crazy Code", but my opponent has Honchkrow GX with "Ruler of the Night" active, which Ability takes precedence?
Even though you're using an Ability to attach the Special Energy card, Honchkrow GX's Ability prevents you from playing it from your hand.

If Weezing has 10 HP left and is Poisoned, would it be Knocked Out before its "Detention Gas" Ability takes place?
No. Even if a Pokemon receives more damage counters from Special Conditions, Abilities, etc. than its remaining HP, that Pokemon isn't Knocked Out until "between turns" is over.

My Active Pokemon got Knocked Out between turns because it was poisoned and Weezing now becomes the Active Pokemon; does its "Detention Gas" Ability work?
No, because you wouldn't replace your KO'd Pokemon until the between turn phase is over. When Weezing comes up, it's too late for Detention Gas at that time.

Can a Pokemon with an attack that does damage to the opponent's Bench get through Mr. Mime's "Bench Barrier" Ability if the Attacking Pokemon has Stealthy Hood attached?
No, it does not get through. The Bench Barrier Ability is not "being done" to the Attacking Pokemon.
