Basic card combo:
Turn 1: Vessel of Nascency
Turn 2: Herald of the Pantheon
Turn 3: Melira, Sylvok Outcast and Greater Auramancy
Turn 4: Shield of the Oversoul and Phyrexian Unlife
Phyrexian Unlife and Melira, Sylvok Outcast prevent me from losing due to life loss, damage, or poison counters.
Greater Auramancy grants enchantments and enchanted creatures shroud. This grants Phyrexian Unlife shroud.
Shield of the Oversoul grants Melira indestructible and shroud (due to Auramancy)
This combo makes the deck invulnerable to almost anything but board wipes, counter-spell decks, milling, sacrifice, and other winning effects.
Vessel of Nascency and Commune with the Gods are to help find the combo and put cards into the graveyard.
Starfield of Nyx and Debtors' Knell are for graveyard return. This helps lessen the blow from milling, counter-spells, board wipes and sacrifice abilities. It also allows me to attach auras to my shrouded creatures.
Starfield of Nyx turns all the enchantments into creatures. This allows me to grant temporary indestructibility to all of my enchantments with Dauntless Escort if a board wipe is played. Avacyn, Angel of Hope is for granting indestructibility permanently.
Since all enchantments would be granted shroud, Ethereal Armor should be extra powerful, and Starfield of Nyx should turn the enchantments into a swarm.
The deck has a good splash of status effects, including first strike, indestructible, vigilance, and flying.
Herald of the Pantheon makes all enchantments, including gods and Eidolon of Blossoms, cheaper and adds quite a bit of life gain. Eidolon of Blossoms adds extra drawing to help find the combos.
