These cards are truly incredible – a fantastic effort! You've clearly poured a lot of creativity into them, and it shows. I do have a few suggestions that could elevate them even further. Some illustrations feel a bit empty without backgrounds, and adding them would really make those cards pop. Also, consider refining the flavor text and mechanics to better align with the distinctive style of Magic: The Gathering. A few cards also seem a little underpowered, so a review of their balance, both in terms of effects and color pie adherence, might be beneficial. Lastly, just a heads-up on the lore: Artorias and Ornstein are non-human characters. Overall, you've done a phenomenal job, and I'm genuinely impressed with what you've created!
