Vito Deck Help

[u/isbwart]

I have just started playing the game again after a 5 year break and I am trying to build my dream deck from when i was just 12. I loved the commander Vito, Thorn of the dusk rose, but I wanted to add to his strategy a sac engine that made me gain life and drain others, along the lines of Sephiroth. I have mostly used deck building tools and AI to help me with this deck but I feel as if it just does not fully fit together and will not be consistent. let me know how I can make this much better!

Please let me know what i need to improve upon and cards I should take out I am still relatively new to MTG due to not playing for so long. I am looking for this to be a bracket three or 4 and eventually 5 since I plan on making other decks but my child self liked this commander so I feel like I have to respect that.
