Omega Barrier - Pokémon Rulings Compendium

I have 5 Pokemon on my Bench, and 2 of them have the "Omega Barrier" Ancient Trait. If my opponent plays Avery and I choose the 2 Pokemon that have "Omega Barrier", do they get discarded or is the effect of Avery blocked?: Yes, they get discarded. The discard effect of Avery is on you, the player choosing the Pokemon, not on the Pokemon with Omega Barrier.

If my opponent's Active Pokemon has the "Omega Barrier" Ancient Trait, can I use Lysandre to switch one of my benched Pokemon with it?: If your opponent's Benched Pokemon has "Omega Barrier", then Lysandre's effect will be blocked. But choosing a Benched Pokemon without "Omega Barrier" will cause it to switch with the Active Pokemon because the Benched Pokemon is the target of Lysandre.

If I use Escape Rope but my opponent's Active Pokemon has the "Omega Barrier" Ancient Trait does he or she have to switch it? Or if they have a Pokemon with "Omega Barrier" on the bench can he or she choose that and not switch it to Active?: If your opponent has an Active Pokemon with "Omega Barrier", then Escape Rope's effect will be blocked. If a Pokemon with "Omega Barrier" is on the bench, choosing that Pokemon will not stop the effect as the Active was the target of Escape Rope.
