If I use Darkrai GX's "Restoration" Ability and then somehow it gets back into the Discard Pile (e.g. Parallel City, followed by Field Blower), could I use "Restoration" again to retrieve it from the Discard Pile?
Yes, whenever Darkrai GX is in the Discard Pile, you may use Restoration during your turn as long as its Ability has not been disabled.

If my opponent used Turtonator GX's "Shell Trap" attack and I have Magearna EX with the "Mystic Heart" Ability in play, will my Pokemon with Metal energy attached get the 8 damage counters from "Shell Trap" if I attack and do damage to Turtonator GX?
No, it will not receive the 8 damage counters. Mystic Heart prevents all effects of your opponent's attacks, and Shell Trap's damage counters are an effect of your opponent's attack.

Does Seviper's "More Poison" Ability stack with the effect of Toxapex GX's "Super Intense Poison" attack?

Does Seviper's "More Poison" Ability stack if I have more than one of them in play?

If I have Darkrai-GX in my discard pile but no Darkness Energy, can I use its "Restoration" Ability?

Can you use Dusknoir's "Dark Invitation" Ability if your opponent's Bench is full?
No, you may not. 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.

If I put a Charizard GX in play using Ho Oh GX's "Eternal Flame GX" attack, and my opponent evolves into Porygon-Z and uses its "Initialize" Ability, does Charizard GX go back into my hand?
No. Charizard GX is in play as an "unevolved Pokemon" and so is not affected by the Ability.
