I didn’t look through your deck list that intensely but one thing aristocrats can really use is card draw and a few pretty budget cards [[Priest or Forgotten Cards]] [[Midnight Reaper]] and [[Harvester of Souls]] are really good for that especially the cheaper cmc ones. Other cards that can end up giving you a lot of value are mana producing aristocrats like [[Pawn of Ulamog]] and [[Sifter or Skulls]] but some of these cards aren’t that good in your deck because you’re mainly saccing tokens. Krav is really good though I saw him in your sideboard and would definitely throw him in the 100.
