If I have no Benched Pokemon and attack with Tornadus' "Hurricane", do I have to discard an energy?
No. If you have no Benched Pokemon there is no place to move an energy card, so you would not do that part of the attack.

The version of "Gyro Ball" attack on Forretress says "you may switch..." as an optional action, but the version of "Gyro Ball" on Ferrothorn indicates the switching part of the attack is mandatory. Which way is correct?
The effect may vary from card to card, so you should play each attack as it is written on its card. So for Forretress the switch is optional, but for Ferrothorn it is mandatory.

If I have a Rainbow Energy attached to Simisage, would its "Fire's Power" attack put a Burned Special Condition on the Defending Pokemon?
Yes, Rainbow Energy counts as all types of energy when in play, so it would count as Fire for that purpose.

If Gothitelle is Active, does its "Magic Room" Ability prevent the opponent from playing older pre-BW Trainer cards that don't say Item on them?
Trainer cards from Diamond & Pearl through Call of Legends should be considered "Trainer–Item" cards. So the older Trainers would be blocked, but not Supporters or Stadiums.

If the Broken Time-Space stadium is in play, can I use Rare Candy on a Basic Pokemon that just came into play this turn?
No, the wording of Rare Candy specifically says "you can't use this card during your first turn or on a Basic Pokémon that was put into play this turn". Broken Time-Space does not allow you to override that.

Machoke's "Knuckle Down" attack says the amount of damage is "not affected by Poke-Powers, Poke-Bodies, or any other effects on the Defending Pokemon". Does that mean it ignores Weakness & Resistance too?
Weakness & Resistance are not considered as effects on the Defending Pokemon, so they are not ignored.

If Zoroark uses "Foul Play" to copy Blastoise's "Hydro Launcher" attack, do I have to be able to return 2 Water Energies to my hand in order to do the 100 damage?
No, the attack does not say "in order to" so you do as much of the attack text as you can.
