Red Cards in Decklist (Vintage)

[pushbyte]

I am having an issue with some cards showing as red in the decklist view for a deck that I imported from my Dropbox account as a .dec file.

The deck is set, and built, as a Vintage deck and things like Mana Confluence and Serum Powder show up red for some reason. There are more cards which do this, about 10ish in total out of 75.

Can someone explain what this means, and if it is due to a bug or problem, then explain how to fix it? Thanks!

When it's red, it means it's banned. It's probably a bug, or a problem with the .dec file.

{Mana Confluence} and {Serum Powder}?

When it's red, it means it's banned.

That's the idea indeed.

(...) a problem with the .dec file.

No, once the data was loaded from .dec file, it is not to blame. Good to have objective confirmation that .dec importing from Dropbox works, thanks!

I put the cards from my new deck, brought from shop, Radikar's Rage and 95% of them are red if they are banned why would they be in a premade deck.

Mayhaps it is a bug?

It has now changed to every card.

Is it because of missing price data?
