10% of the deck is already some form of draw or tutor so I really don't think I need more unless you can name some direct upgrades to what is already present.
Cemetery Recruitment is a better option for recursion than
Recover, and while I did run it for a bit I've moved away from non repeatable recursion for the most part. At the moment my only real debate on recursion options is
Gisa and Geralf vs
Phyrexian Reclamation. Higher upfront cost, cheaper long term, limited to Zombies vs Lower upfront cost, higher long term, can get the few non Zombies as well.
Gleaming Overseer is kinda iffy. Menace is nice but limited to just my tokens, and I've got
Graf Harvest in for cheaper and more widespread Menace, while Hexproof is completely pointless on the tokens. People aren't going to waste single target removal on some 2/2 Decayed Zombie, they're going to pop off a board wipe to get them all.
Eternal Skylord is just bad. Flying only for tokens at the same cost as
Hordewing Skaab, which does it for every zombie and gets me more cards, and for a higher cost than
Geralf, Visionary Stitcher, who again does it for everything.
