Magearna-EX and similar cards ruling questions

[Zeatap]

I've encountered this interaction online with Ptcgo and I am wondering if that is how it's supposed to work.

I've used Guzzlord's (CEC136) Red Banquet attack to KO an active Pokemon which had a Metal Energy attached with Magearna-EX on the bench. I was not allowed to take an extra prize. Is this correct?

Follow up if that is correct, does Magearna prevent the effect of ADP's GX attack if the conditions are fullfilled? Does Big Parasol prevent these effects? Does Wonder Energy prevent these effects?

Thanks for asking these questions! One resulted in this ruling:
If my opponent uses Guzzlord's "Red Banquet" attack and my Active Pokemon with Big Parasol attached gets KO'd, does my opponent get to take an extra prize for "Red Banquet" or not?Big Parasol prevents all effects of attacks from your opponent's Pokemon done to your Pokemon; but taking an extra prize is a game effect, not "an effect done to your Pokemon", so your opponent gets to take the extra prize.

Also:

ADP "Altered Creation" GX attack creates a global effect that is not prevented by effects that protect a specific Pokemon, such as Big Parasol, Wonder Energy or Mystic Heart.
