Aristocrat players - HELP

Hi everyone!

I'm a huge Final Fantasy fan, and I'm super excited to build a Commander deck around the new [[Sephiroth, Fabled SOLDIER]] card.

This will be my first ever Aristocrats deck, and to be honest, I don’t have much experience with either the archetype or playing Black in general. I’d really appreciate any tips, feedback, or insights from more experienced Aristocrats players!

I’ve put together a rough list based on other established Aristocrats commanders, but I’m sure there’s plenty of room for optimization to better suit Sephiroth’s abilities.

Here’s the decklist (with tags included):

Any advice on what to cut/add and Aristocrats in general would be greatly appreciated.

Thanks in advance!
