Does Archeops' "Ancient Power" Ability stop attacks that evolve Pokemon, such as Karrablast's "Mysterious Evolution"?
Ancient Power only prevents you from playing Pokemon from your hand to evolve other Pokemon. Mysterious Evolution's effect is not stopped because it evolves the Pokemon from a card in the deck, not a card in your hand.

Does Hydreigon's "Dark Aura" Ability override the original type of attached energy, or is it in addition to the energy's original type?
Dark Aura replaces the attached energy's original type or types with Darkness type. In other words, a Fire Energy card no longer provides fire energy when Dark Aura affects it.

What happens to Rainbow Energy when it's attached to Hydreigon? Does "Dark Aura" Ability change it to ONLY produce Darkness Energy rather than all energy types simultaneously?
Since Dark Aura replaces the attached energy's original types with Darkness type, Rainbow Energy would lose its effect to produce all types of energy while Dark Aura is in effect. However, Rainbow Energy is still considered a "Special Energy Card" in this situation.

If Magnezone has Special Energy cards attached and discards all of them when using its "Lost Burn" attack, can it do damage to a Scizor that has the "Red Armor" Poke-BODY?
No. First choose which energies to put into the Lost Zone, then do the damage (before any other effects), then you actually put the energy into the Lost Zone at the end of the attack. So it will still be attached at the point when damage would be done, but the damage will be blocked by Red Armor.

If Pidgeot attacks with "Headwind" against Yanmega with the "Insight" Poke-BODY, will "Headwind" increase Yanmega's attack costs or will "Insight" reset them to zero?
If an Attack Cost is set to zero by an effect, it cannot be increased. Note this is different than an Attack Cost that was reduced to zero by subtraction. Once a Pokemon's Attack Cost is set to zero by an effect, it stays at zero until that particular effect wears off.

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 Pachirisu's "Self-Generation" Poke-POWER is used to attach two Lightning Energy to Pachirisu, and the opponent has 4 Ampharos Primes with "Conductivity" in play, what is the result?
Pachirisu would be have 8 damage counters placed on it due to Conductivity.
