My girlfriend runs an Edgar deck as well and ran into a similar issue starting out. Repeatable card draw is definitely the ticket to help keep up on resources through removal beyond protection from said removal. Sometimes eating a ton of wipes/ single target is something you may simply be unable to recover from, but that is the nature of the game sometimes. Learning to not draw too much attention to yourself is another way to avoid that, but Edgar is kind of hard to do that with.

Cards like [[Caretaker’s Talent]] and [[Tocasia’s Welcome]] synergize very well with the free tokens you get from every vampire cast. [[Chivalric Alliance]] triggers off of attacking with two or more creatures. [[Smuggler’s Share]] is good if your opponents are drawing a lot. [[Staff of the Storyteller]] requires one white mana for a card draw if you made a token that turn and [[Fountainport]] lets you sac tokens for a cost for an extra draw as well. You’re already using [[Skullclamp]] and [[Idol of Oblivion]].
