I´m not sure, if i understood everything...but i can tell how i figuered it out: It´s all death cards, so i assumed a death card as the hidden price card.
The second point was the order of the cards, the mana is decreasing.So between 7 and 4 is 5 and 6. That´s was why i assumed a 5 or 6 mana card. Then i looked up all 5 and 6 mana death cards and ended up with vampire as a synonym is "leech" and it has a "l" (First i missed the hint with the 7 letters...). After you told me that leech is not correct i looked up some synoym for vampire and yeah...it jumped in my face...DRACULA, of course :D
I had a lot of fun with that! To be honest, we had a lot of fun with two mperson ;) May be you motivated me to start my own Giveaway with a little riddle. Thank you for that!

That's right, this was a major clue 😁

Interesting. This was a coincidence. I haven't thought of ordering it that way haha. So this is me saying there's a different trick to it.
