Keep queueing after you remove the Golden Core Set cards, this is likely because the person you were to be matched with has Golden Core Set cards in their deck (as mentioned above).
Thanks for your hard work today. Can confirm: no golden core set cards is the solution. Don't give up after first try, as you may queue into someone with a bad deck.

Sorry for this friends, definitely a frustrating issue. The team is working on it as we speak, updates here.

FYI: It seems that a workaround is to remove all golden core set cards from your deck!

We are updating the known issues list now, thanks!

See what I wrote above:
"If you still get the error when you queue, it's likely because the person you were to be matched with has Golden Core Set cards in their deck."
