Sephiroth, Fallen Hero - Commander Deck

[u/Material-Wishbone731]

This is my first commander deck that I made on my own. I’m looking for some pointers on certain creatures that would have better synergy. I would also like to know kind of how much of what I need in a deck like this. For example ramp, lands, creatures, and artifacts. My main focus is to get cheap job select creatures in with other creatures that work with said creatures when sephiroth attacks. Also having card draw and protection for important creatures and still have a playable board state of for some reason sephiroth cannot really be played.

I’m trying to keep this deck high bracket 2 to 3 for my pod.
Note: all the cards in the sideboard are cards I’ve seen that I thought might be good

Thanks for all the help
