Debt to the Deathless?

I'm not sure about Debt to the Deathless I feel like I'd really only find it useful in a multiplayer match. Sideboard perhaps?

I like it

I am not really good with enchantments so I don't really have any card suggestions

I would suggest making the deck more predictable to play with though

I would sideboard cards such as agent of erebos and harvestgaurd because they are only good against some deck types

In return I would raise the number of other creatures that you have

This deck hurts alot. I would know, i got pillow forted to death by it. Definite +1 from me. My only suggestions are Vizkopa Guildmage, Sanguine Bond, Exquisite Blood, and maybe Blood Reckoning.

Greater Auramancy is great in decks that run a lot of enchantments. I think it would be especially useful in this deck as most of your creatures are also enchantments. Maybe as a two of.

I'm not so sure about Greater Auramancy. Aside from being a little too high for my budget, it would prevent me from putting auras like Gift of Immortality on my creatures.

this looks like what my orzhov enchantment deck looked like in in the beginning, Orzhov Blood Magic, ill put mine in for inspiration. try going for a more lockdown form of control. Shrieking Affliction and Thoughtrender Lamia are good additions id also recommend more mana fixing like guildgates and the bounce lands from old ravnica if you want to stick to het budget options. id drop baleful eidolon and harvestguard alseids for a singleton of Erebos and Atheros, and maybe change the auramancers for the river trawlers. if you can bump the oppressive rays to the full set of banishing lights, and Brain Maggot is such a wonderful cards in this deck it would be better than thoughtsieze and cheaper too

why not Odunos River Trawler?

I've considered River Trawler for this deck, but the main issue is it only brings back creatures. Auramancer is a bit more versatile in terms of what she can bring back. Sideboard perhaps?

true

you may use cards like Conjurer's Closet or return to hand effects to trigger more constellations or reuse Auramancer

Soul Tithe (or any 1 time use enchant) + Sun Titan: maybe xD
