First time looking at any of this despite scrolling past the thread several times, so forgive me if I retread ground made mention of in previous threads. I'm going to set aside the rules text itself since I know basically nothing about the gameplay beyond what I can glean from the text on this one card.
>text box
I like the idea for the "scroll" to sort of be spilling out of the frame like it's been draped over the border for the art. I'm wondering if you could find a way to incorporate the type line more cleanly, sort of like 
>>96872242 this one, but with in a way that makes it pop more. I prefer the type being at the top of the text box, but maybe you could try offsetting it to the left with a bit of typographical flair like pic related to make it feel more like the opening to a ye olde document.
>the border
I think it's good to have one, but to keep it thin so the art has room to breathe. 2 and 3, without the frame, make the art look like something stretched out on a canvas, which is an interesting visual design, but I think a minor border along the edge would help the card feel more "complete." 
>header
How expansive do you plan on making card names? This card's name is only two words, so it's easy to fit, but do you expect to have longer names? A more standardized font size will help the cards look cleaner, so you might consider whether you'll need to allow for multiple lines for names/titles or if you're just going to adjust font size per-card.
