Ok some of the cards in my decks aren't showing up
Which ones show us some examples
Do you mean the image or te entire cards data page? If you mean the picture, go to Settings> Database Manager> Purge Images. This is 'drastic' to fix one card's non-image issue but it from my understanding when it happened to me months ago, it was just an issue with the initial downloading of the image. It didn't get the whole file in time and it now believes that blank screen IS the image. So purge away, my friend. 😊
However, I have no explanation if the card itself is not showing up in the database. Sorry. 😳
Also, images for certain cards, particularly special printings and promotional versions, aren't in the database.
Ic ic Here's my example {bloodmark mentor}
See, the version of that card is from Duels of the Planeswalkers.
Online card versions are the ones missing(mtgo and dotp)
