Need:
Hubris
Fumble
* Valduk, Keeper of the Flame - Go wide instead of tall
$ Umbra Mystic
Felidar Umbra - Protection and lifelink, and it can even be moved around
$ Daybreak Coronet
$ Kor Spiritdancer
$$ Retether
$ Three Dreams - Tutor for 3 auras

Consider (have):
More auras
Sram - Another enchantress
Jeskai Ascendancy - Loot and pump
Archon of Sun's Grace - Smaller token producer
Enlightened Tutor
Plea for Guidance - Double Idyllic Tutor
* Stubbon Denial
* Leyline of Anticipation
Boros Charm - Protection or suddenly finish someone
Dovin's Veto
Negate
Sun Titan
Heliod, God of the Sun - Give vigilance and make dudes that can carry auras and buff Ethereal Armor/All that Glitters
Thought Vessel
Mirrormade
Grand Arbiter Augustin IV
Puca's Mischief - More trades
Kykar
Crab Umbra - Protection and pseudo-vigilance
Boonweaver Giant
Curiosity
Triclopean Sight - Vigilance to stay safe
Knightly Valor - Vigilance, a small pump and a small dude I can donate
Siren Stormtamer, Alseid of Life's Bounty - Can protect a suited up dude, or be suited up itself
Shu Yun
Daxos of Meletis
Willbreaker
Ajani, Caller of the Pride
Akroan Horse
Steel Golem - More traditional Zedruu, stopping an opponent from playing threats/blockers
Goldnight Castigator - Lets Zedruu kill faster, but if I don't have unblockable they can just block with this, and the body is not insignificant as an attacker either
Mana rocks - Talisman of Conviction/Creativity, Darksteel Ingot
Harmless Offering - I don't really have as much use for this as a regular Zedruu deck, as I'm likely to have Zedruu out when I have something to give away
Elspeth, Knight-Errant - Jump Zedruu or get some chumps to give away
Time Wipe - A board wipe that lets me evade commander tax
Commanding Presence - Can make dudes to give away every turn, but if I'm connecting with a big Zedruu I'm probably doing fine already?
* Corrupted Conscience - Give infect to Zedruu, or just steal a big dude and give it infect. Currently used in Braids
Totem-Guide Hartebeest - A more expensive Heliods Pilgrim
Cartouche of Solidarity - Gives two things to donate, but first strike might not be very useful
Battle Mastery - Is just double strike enough to be worth it?
Holy Mantle - Pump and unblockable
Faith's Fetters, Stasis Snare - Removal that I can donate, but only deals with creatures
Sphere of Safety, Ghostly Prison, Propaganda - Stay safe
Traveler's Cloak - Cantrip aura with evasion
Pentarch Ward - Cantrip with evasion/protection
Kher Keep - Make dudes to give away, but it is a colorless land
Whitewater Naiads - Each aura gives unblockable until end of turn
Chariot of Victory
Sentinel's Mark

Consider (don't have):
Flickerform
Whirlwind of Thought - Basically an enchantress
Spirit Mantle - Cheap aura with a slight pump and unblockability through pro creatures
Open the Armory - Aura tutor
Elemental Mastery - If they have a lot of chumps, go wide instead
Spectra Ward - Protection from targeted removal and unblockable by colored creatures, but makes it hard to put more stuff on my dude
Tilonalli's Crown - Give trample, but might not be worth a card and 2 mana with the minor pump
Clout of the Dominus - +2/+2 haste and protection, but shroud is a problem if I need to add more enchantments after this
Squire's Devotion - Lifelink and a small dude to donate
Deep Freeze - Commander removal
Indestructibility
Drake Umbra - Evasion, pump and protection
Aether Tunnel - Unblockable
On Serra's Wings - Evasion, lifelink and a little buff
Angelic Destiny
Arcanum Wings - Evasion that can sneak in an expensive enchantment
Cartouche of Zeal - Surprise attacker that removes the one blocker they left behind
Celestial Mantle
Nomad Mythmaker
Curator's Ward

------------------------------

Considered cuts:
Whispersilk Cloak, Lightning Greaves - Shroud could be a problem for suiting up
Sol Ring - With a lot of cheap encbantments, I might not have use for 2 colorless very often
Banishing Light, Oblivion Ring, Grasp of Fate, Imprisoned in the Moon - I do need some removal, but are the board wipes enough?
Counterflux - I should probably have some
Messenger's Speed, Escape Velocity, Footfall Crater - Might not need this many haste enablers in addition to boots
Tragic Arrogance - Removes most of my buffs, but could be good if I donate away some of them first
Scourge of the Nobilis
Asha's Favor

----------------------

Cuts:
Messenger's Speed - Replaced with the less fragile Footfall Crater that can replace itself if redundant. Although the trample on this could be important at times
Faith's Reward - I usually can't sit back holding up 4 mana in case I need this
Racecourse Fury - Enough haste enablers
Sigil of the Empty Throne - Probably more needed in Karametra
