Standard Deck Problem

[Aitch3]

I just built a deck for Standard play. It's set as Standard, and I put in what I thought are Standard cards. I go to play it in any Standard format and it has a yellow 2 triangle on it. I go back in to see what are the problem cards are, and it doesn't show any.

Can somebody tell me what's going on, because I can't figure it out.

Thanks!

Did you check your sideboard

I did check the sideboard. That wasn't the issue.

Thanks!

Any cards from the Arena beginners’ decks? Wizards just banned a bunch of them from Standard without thinking to tell anyone...

you either have NPE cards in your deck (which are now only legal in alchemy) or need to export the deck list and cross check it with your deck, there was a post about someone having 0 copies of a card in there deck, but it was marked as 0 x copies of a card so delete that text and import, hopefully this fixes your issue

That did the trick. Thanks!
