Abilities » Stance Change
If I use Aegislash's "Stance Change" Ability, to switch for another Aegislash, can I then use the new Aegislash's "Stance Change" if I want to?
No, even though you have switched to a new Aegislash card you cannot use Stance Change again because the effect of using it remains on that Pokemon.

Abilities » Upside-Down Evolution
If I use Inkay's "Upside-Down Evolution" Ability, does it remain Confused after evolving?
No, it does not. The phrase "this counts as evolving this Pokemon" refers to evolution rules that remove Special Conditions on that Pokemon.

Abilities » Toolbox
If Sigilyph with the "Toolbox" Ability has Plasma Badge and Reversal Trigger attached, do I get to search my deck for a card when it is KO'd by an attack?
Yes, you can. The tools are still present on the Pokemon when it's KO'd (assuming the attack does not discard the tools first), so you would get to use the effect of Reversal Trigger since Plasma Badge makes Sigilyph a Plasma Pokemon.

Can you attach more than one tool of the same name to Sigilyph with the "Toolbox" Ability? And if so, do the effects of the tools stack?

If Sigilyph with the "Toolbox" Ability gets attacked with something that discards a Pokemon Tool who gets to choose which tool gets discarded?
If an attack says to discard a Pokemon Tool it will discard all tools attached to that Pokemon, not just one. So poor Sigilyph would lose all of his tools.

Abilities » Verdant Wind
If I have Virizion EX in play and use Hydreigon's "Dark Trance" ability to move a Blend Energy GPRD onto a Pokemon affected by a status condition, will Virizion EX's "Verdant Wind" Ability remove the Special Condition?
Yes, it does. Any time a Grass Energy card becomes attached to a Pokemon while Verdant Wind is enabled causes Special Conditions to be removed.

If I have Virizion EX on the bench and my Active Pokemon has a Grass Energy attached, would my opponent be able to play Hypnotoxic Laser since the Pokemon with Grass Energy attached "can't be affected by special conditions"?
The opponent can play Hypnotoxic Laser, but its effect would be blocked.
