Old Parallax styles prevent new cards being added to a SEALED deck.
Here is a weird bug from my sealed pool. It's showing the parallax version of Snakeskin in my pool, but I don't own it. When I go to add it to my deck, it brings up the prompt to buy the style instead of being able to add the card. Appears to be no way to get around the style. D:
Figured out the cause of this bug in sealed. I had the parallax style set as my default for a previous version on Snakeskin. (Had same bug with Take Up the Shield and for the same reason)
This makes the parallax style for the current set the default. Since I don't own the current style, it makes me want to buy it. There is no way to add the card to my deck since clicking it only brings up the buy option.
If I set the default style of the old Snakeskin card in my collection to a non-parallax version, then the sealed pool defaults back to normal style and I can add it to the deck again.
