Forgotten Perils Bundle
I purchased the Forgotten Perils bundle only to find that I can't use the Resplendent Angel card style with my M19 copies. I didn't realize that I would need the LCI version of the card in order for it to work, as I did not see that mentioned anywhere.
There is no reason for me to spend wildcards when I already have four copies of the M19 version. There should be a clearer warning that a style can only be applied to one version of a card, or better yet, allow styles to be applied to other printings.

Card styles have always only been usable by one version of a card. That's why the card styles all have the set symbol still on them, to let you know which version can use it.
