Gameplay » Cards in General
What is a marked card?
A card that you can tell what it is by a glance (without seeing the front). It might have a different back, be scratched or written on in some way, be more worn out than the other cards, etc."

Attacks » *Attacks in General
When a card's attack "does damage to itself", is this damage considered to be an ATTACK against the Defending Pokémon? Let's say you had an Electabuzz versus a Team Rocket Porygon and Team Rocket Porygon switched Electabuzz's Weakness to Lightning. You Thunderpunched with Electabuzz and flipped tails. Would Electabuzz receive 10 or 20 damage? Furthermore, would Defender prevent this damage? (Defender prevents damage from attacks).
1) 20, it is considered an attack. 2) Well, assuming it was an attack that did damage to itself, then Defender would help with that damage.

Gameplay » Evolving/Devolving
You ruled that Team Rocket's Magikarp's Rapid Evolution can be used the turn those Pokémon come into play [Ed.Note: see also "Rapid Evolution" (Jul 13, 2000 WotC Chat Announcements)]. Does that mean that if I had played TR Magikarp down on the first turn of the game, I could evolve him (I know that this is not possible, i.e., I cannot get 3 [W] Energy on Magikarp but if we ignore this limitation) ... would it be possible since Rapid Evolution ignores the normal evolution rule?
Yes, *if* you could get three water energy on Team Rocket Magikarp.

Gameplay » Special Conditions
If you "Paralyzed" your opponent's Active Pokémon and then use an attack that says "Flip a coin. If heads, your opponent's Active Pokémon is now Confused.", is that attack a forced check or optional?
It is a forced check.

Gameplay » Retreating
Can I retreat my Active Pokémon if my bench is full?
Yup, when you retreat you are switching your active for one on your bench.

Energy » *Energy Cards In General
Any card that provides Energy is considered an Energy card of the type it provides. So if you were to Energy Burn a DCE, it counts as a Fire Energy card that provides 2 fire Energy until the end of the turn. So it could be Gathered by Team Rocket Charmander but would only provide 1 coin flip for the Continuous Fireball attack on Dark Charizard.

Attacks » Agility
If my Pokémon uses Agility and get heads then on my opponent's next turn he benches his Pokémon, does that [Ed. Note: Agility's effect] end? If that Pokémon was Knocked Out, would Agility still be on the next Pokémon that he sends up?
Since the Agility Attack references Rapidash, only Benching or Evolving him ends the effect. Also since it only refers to Rapidash it would still be in effect if the other player benched.

At any time during a battle, are you or your opponent allowed to shuffle your deck?
NO! [Ed. Note: This references shuffling at random times, not when appropriate]
