Would the two Basic energy cards attached by Terrakion EX's "Pump-up Smash" attack trigger Ampharos' "Electromagnetic Wall" Ability twice or only once (or not at all)?
Any energies attached from the hand would trigger Electromagnetic Wall, once for each energy card being attached.

Would Giratina EX's "Shred" attack allow my opponent to knock out my Shednija (with "Empty Shell") and take a prize since the attack says its not affected by any effects on the Defending Pokemon?
The damage done by Shred is not affected by Empty Shell, but that has nothing to do with whether you take a prize or not. You still get no prize because of "Empty Shell".

Does Espeon's "Solar Revelation" Ability prevent damage done to Benched Pokemon?
No, it does not. Unlike placing damage counters, doing damage to a Benched Pokemon is not prevented by Solar Revelation.

Does Espeon's "Solar Revelation" Ability prevent moving or placing damage counters?
In the steps of resolving an Attack, moving or "placing Damage Counters" counts as an Effect of the attack; it is not part of "doing damage". Therefore, as an Effect it would be prevented by Solar Revelation.

Does Espeon's "Solar Revelation" Ability prevent the flipping of coins for an attack that does damage times the number of heads flipped?
No, it does not. Flipping coins in this context is used to calculate how much damage is to be done. Since "doing damage" is not prevented, the flipping is not prevented either.

If Cinccino with the "Smooth Coat" ability also has "Rocky Helmet" attached to it, can I choose to activate Rocky Helmet first, and then flip for Smooth Coat?
You would need to know whether Cinccino takes damage or not in order for Rocky Helmet to work, so in this scenario you would have to flip for Smooth Coat first.

If I attach a Rainbow Energy to Shuckle with "Fermenting Liquid" Poke-BODY that has 5 damage counters on it, would it be knocked out prior to its Poke-BODY being applied or would I get to draw the card before it's knocked out?
It is a Poke-BODY that is automatically triggered, so you would get to draw the card.
