For me Sleeve Draw is what I dislike most. I'm sure it's just a matter of getting gud as they say, but every time it's up I tend to tunnel pretty hard on dealing out cards and not other things. Aside from that I feel it plays pretty well/functions well enough. The flavor and uniqueness is definitely missed when it comes to the cards themselves. The naming of Minor Arcana bothered me a bit as well but I looked into the definitions and it... kind of? makes sense:

Major Arcana: This refers to the first 22 cards of the tarot deck. These cards are usually considered to be the key cards of the deck.

Minor Arcana: The subsequent 56 cards in a tarot deck. These cards provide support and nuances to the 22 cards of the major arcana in a tarot reading.

If the cards providing a seal is what makes them "key cards" then that is what makes them "major". Not the % damage increased number. Just my interpretation.
