If Bronzong with the "Metal Fortress" Ability is in play, are benched Pokemon protected from Greninja's "Shadow Stitching" attack? If so, does it also protect Pokemon that come into play on the bench during the opponent's turn?
If Bronzong is on the Bench, all benched Pokemon are protected, including ones put into play after the attack has happened (for example, Shaymin-EX's "Set Up" Ability will work in this scenario); however, the Active Pokemon is not protected, even if it goes to the Bench it will not get its Ability back. If Bronzong is Active and has its Metal Fortress shut off, the Benched Pokemon are not protected; even if it moves to the Bench, it will not get its Ability back. Finally, if Bronzong is on the Bench and becomes the Active Pokemon during your turn, it loses its Ability and the Benched Pokémon are no longer protected.

Suppose that I have a Gourgeist with the "Gourgantic" Ability, with a Grass Energy and Heavy Boots attached and a Training Center in play. Would its max HP be 200 or 250?
Gourgantic essentially replaces Gourgeist's printed HP, so reductions and additions to HP work as normal. You can stack the additional HP effects of Heavy Boots and Training Center, so in this case the resulting HP would be 250.

What happens if I try to use Ho-Oh EX's "Rebirth" Ability but my bench is full? Is the Ability used up, or is it not used and I can try it again later after I have some space on my bench?
If you know the Ability will not affect the game state, you cannot use it. If your Bench is already full, you cannot use Rebirth.

If Marowak's "Bodyguard" ability is in effect, preventing the effects of attacks on me and my hand, does Greninja's "Shadow Stitching" attack turn off abilities of Pokemon in my hand or not?
Shadow Stitching turns off the Bodyguard ability, so until the end of your next turn none of your Pokemon will have Abilities.

If a Pokemon with Bursting Balloon tool attached is attacked by an Yveltal with the "Fright Night" Ability no damage is placed on the attacker, but is the tool discarded at the end of the turn as its text indicates?
The Bursting Balloon damage placement effect is turned off, but the discard text is also an effect, so the tool is not discarded at the end of the turn.

Can I attach a Shield Energy to Lucario with the "Dual Armor" Ability?
It depends on when the Shield Energy is being attached. If Lucario already has a Metal Energy attached to it Dual Armor makes Lucario both Fighting & Metal types, so you CAN attach Shield Energy at that point. However, if Lucario does not already have a Metal Energy attached or if its Dual Armor ability has been shut off, then you CANNOT attach a Shield Energy to Lucario.

If Lucario with "Dual Armor" Ability has one Basic Metal and one Shield Energy attached, what happens if the Basic Metal Energy card is removed? Does Lucario remain a Metal type or would I have to discard the Shield Energy?
Once Lucario gains Metal typing due to Dual Armor it stays that way as long as a Metal Energy is attached. And Shield Energy provides a Metal Energy as long as it is attached to a Metal type Pokemon. So if only the Shield Energy remains, Lucario stays Metal type and the Shield Energy remains attached.

If I have Suicune with the "Wind Charm" Ability Active and my opponent attacks with Greninja's "Shadow Stitching", are all my Abilities turned off including "Wind Charm", or does "Wind Charm" prevent "Shadow Stitching" from disabling my Pokemon's Abilities?
Wind Charm prevents Shadow Stitching from disabling your Pokemon's Abilities. However, if Suicune goes to the Bench, Wind Charm's effect goes away and your Pokemon will no longer have Abilities that turn. Suicune also does not protect any Pokemon not already in play.

If my Zebstrika with the "Zap Zone" Ability attacks a Pokemon with {L} Weakness, does the Weakness get ignored because of "Zap Zone"?
No, Weakness & Resistance are game mechanics, they are not effects that would be ignored because of Zap Zone.
