If I evolve my Shroomish into Breloom (which has the Spore attack), can I use Amoonguss's "Bursting Spores" Ability?
Yes, because you have played a Pokemon that has the Spore attack from your hand during your turn.

Can you use Mawile GX's "Captivating Wink" Ability if your opponent's Bench is full?
No. It's public knowledge that you can't put down any additional Basic Pokemon on your opponent's Bench, so you cannot use the Ability.

Mawile GX's "Captivating Wink" Ability says to put any number of Basic Pokemon you find in your opponent's hand onto their Bench. Does this allow you to put more than 5 Pokemon on the bench?
No, Captivating Wink does not allow you to exceed the normal limits of the game. You can put any number of Basic Pokemon onto your opponent's Bench up to the maximum size of the Bench.

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.
