i own a Edgar deck and there is one thing to note: he is the perfect sac victim. I didn't realize this until i was able to stall the game for a few turns by negating attacks from the votlron player by using [[Martyr's Cause]] and Edgar, saccking him to get 2 vampires to then withstand the voltron blows and finally i draw a boardwipe. I am looking at your list and there are many unusual cards, it seems you want to build him as more of a control deck. as it has been said before the deck is still not too focused but you can actually build him more into an aristocrat deck if u wish so which would not need to rely too much into the vampire side. there are plenty of super cheap sac outlet like [[Nantuko Husk]] to use
a good start is also Edhrec, you can have a sense of the deck here - i choose for you the non-vampire but budget decklists - https://edhrec.com/commanders/edgar-charmed-groom/lifegain/budget
it's still heavily populated by vampires though. I honestly like the amount of unusual card you did find out and I would go in that direction - this could be a more deck-centric deck than the usual commander deck
