Attacks » Feint Attack
If Shiftry uses "Feint Attack" against a Pokémon that successfully used "Agility" the previous turn, would Agility prevent the Feint Attack or not?
No, the Feint Attack ignores any effects on the Defending Pokémon, including Agility, Wonder Guard, etc.

Attacks » Feint Attack
If Shiftry uses "Feint Attack" against Whiscash with "Submerge" Poké-BODY on the bench, which one prevails? The attack or the Poké-BODY?
Feint Attack ignores ANY effect on that Pokémon which attempts to prevent its damage; the attack itself specifically states that the attack's damage isn't affected by Poké-Powers and Poké-Bodies (and other things as well).

Trainers » Rare Candy
Could you Rare Candy a Pokémon and NOT play an evolution on it just to get rid of the Rare Candy?
No, you cannot discard a card for free. You must be able to attach the Stage 2 card, or you cannot use the Rare Candy.

Errata » Magnemite
I got a Reverse Holo Magnemite, and the resistance symbol is an empty white circle (like the colorless symbol without the star in the middle).
It's just a grey circle (means nothing) where the foil is normally cut out for Resistance. However for clarification, there should not be any Resistance on that particular card - the non-foil of that version doesn't have a Resistance either.

Errata » Balloon Berry
In the Japanese card, there is a text saying "If Balloon Berry is attached to one of your Pokémon, the Pokémon.'s retreat cost is 0". So, you should play Balloon Berry as if it negates the Pokémon's retreat cost while attached to that Pokémon, not just when it actually attempts to retreat. For example, Muk-EX's "Slimy Water" attack damage will be reduced to only 40 against a Pokémon with Balloon Berry attached to it.

Trainers » *Trainers in General
Could I use the effect of a Stadium card already in play, then play a Stadium card from my hand to remove the old stadium, and still be able to use my new stadium's effect?
Yes, provided you have not already played a Stadium card that turn [and the new one has a different name].

Gameplay » Evolving/Devolving
A guiding rule for evolving Pokémon... If it's not in play at the start of that player's turn, it can't be evolved normally. And effects that say "this counts as evolving the Pokémon" count against being able to evolve a Pokémon normally afterward. So, you can use Wally's Training after evolving normally, but you can't use Wally's Training then evolve.

Trainers » Rare Candy
Can I use Rare Candy on a Pokémon that has already evolved normally that turn?
No you cannot, because Rare Candy can only evolve Basic Pokémon If you evolved a Pokémon already this turn, it would not be a Basic any more.

Trainers » Rare Candy
Can you use Rare Candy to evolve a Mysterious Fossil into an Omastar or Kabutops, or use it on a Root/Claw Fossil to evolve into Cradily/Armaldo?
It can. It counts as a basic Pokémon while in play. Omastar, Kabutops, Cradily, and Armaldo are Stage 2 Pokémon; you could use Rare Candy on the Fossil trainer to skip to them.

Gameplay » Special Conditions
In the new Tournament rules, it is said that when time is called, the active player is allowed to finish his or her turn. After this, do players still check for Burn, Poison, and other relevant Special Conditions, or is the game over before the Special Conditions can take place?
When time is called, the end of the game would trigger at the end of the current player's turn after resolving all of the effects that occur during that player's turn, but before addressing any actions that happen between turns such as Special Conditions.
