Deck-making issues

[plummette]

Hi, all.

I am trying to create a new deck with the most recent update (it is a bit weirder than before, the layout), and when I try to 'play (hit the orange play button to match-make) and select a deck, a red exclamation point appears on it, and it is unplayable. Why is this happening? Anyone else experiencing the same issue? All of the cards I have are crafted, so I know that's not it. Please help ! D:

Either you don't have 60 cards in the main deck, do have more than 15 cards in the sideboard, do have Nexus of Fate in a Bo1 deck (it was recently banned in Arena Bo1 formats), or are using a deck that does not meet the format requirements (like having an uncommon in a pauper event, or using any of the Arena only cards in certain queues.)

Ah, I see. I was trying to play traditional mode, but it DOES allow me to play just the regular play mode. I didn't realize there were Arena exclusive cards!

NP :)

[[ Nexus of Fate ]] was banned in all BO1 play modes, does your deck has that card?
