Hello! I have a few reflections on your game.
First, I agree with the person that suggested adding a note about when you may be prompted to draw a Major Arcana card. The easiest place would be in smaller letters under the Ace heading. This would remind players at glance while they're immersed.
I think, and I'm not pandering, that there's something simple but elegant about the world you're offering players. It's very fertile ground. I do wish there was a bit more for players who have "imagination trouble". Specifically, those who see the invitation to list ingredients and sigils for a learned spell- I've seen those folks on Reddit and I know that would send them into a panic. I'd suggest prompting the player to use attributes of the card for inspiration. That's just a suggestion you can take VERY lightly. Not every game needs to help those on the visualization-struggle-road.
The one thing I would suggest, and this may or may not be easy for you, is to have a printer friendly version of this game. It practically begs to be played at a table and away from technology. Maybe even played in a (hopefully not windy) park or botanical garden if possible. Perhaps even a candle-lit room or on a a porch as the sun sets.
There's a lot to think about here for players who can give themselves over to the fantasy. The notes on it being cozy help reinforce the vision you have from the background as the creator.
