Ahh, glad I'm not alone when it comes to judging the cards. I used to have old collections of fan made ones but I most of them prefer doing official cards (which means I only change the pictures, nothing else).
No seriously, it's perfect. I personally would have designed it as an equipment, but your design is just perfect the way you approached it. Two different solutions give different takes on the same card. I love these kind of cards. I really do.
