So I was in a game vs a combo priest in standart. I got lazul, opponent had 3 cards in hand but Lazul gave me only 2 options. It happened at the very end of this replay:

If anyone has any idea why that happened please tell.

at this turn

I guess your opponent had two copies of the same card in hand and maybe discover effects never show duplicates, but I'm not sure...

Here, I found it:

"Discover effects will not present duplicate options: each of the three possible choices will be different."

Thanks so much! I almost lost my mind yesterday trying to figure this out :)

 Is there any way to be sure you did not?
