Goal of the deck is to lock the opponent out of doing anything with cards like Blood Moon, Ghostly Prison, Magus of the Moat, and Ixalan's Binding while drawing tons of cards with Sythis, Harvest's Hand and the like. With our card drawing creatures, Abundant Growth turns into the ultimate cantrip. THIS DECK DRAWS SO MANY CARDS. You draw so many cards that you'll have to discard sometimes. Your card draw engine has some form of protection too because Eidolon of Blossoms and anything enchanted with Angelic Destiny will have shroud because of Greater Auramancy.
The prison for this deck actually feels very effective because with 4 Seal of Fire and Oblivion Ring and Ixalan's Binding you can remove some troublesome cards from your opponent that don't rely on attacks. Most cards that can't be dealt with by a Seal of Fire are probably a non-issue because Magus of the Moat or a couple Ghostly Prisons will keep them at bay. Good luck getting rid of any of them in a hurry either because 3 copies of Greater Auramancy will be a real pain. Also, Hall of Heliod's Generosity can bring back a crucial enchantment your opponent was able to deal with.
The win conditions for the deck is, for one, simply get Angelic Destiny on any of your creatures and then start swinging. Angelic Destiny is a really fast clock that is hard to deal with if you have a Greater Auramancy in play. Secondly, Sigil of the Empty Throne can also win on its own and the tokens can even be enchanted with Angelic Destiny to make a near unbeatable creature.
Resurgent Belief or Open the Vaults usually just ends the game because if your opponent already used all their enchantment/permanent removal (ex. Abrupt Decay) on your Blood Moon, Oblivion Ring, Runed Halo or whatever, then they are all coming back at once. When they all come back, you will also probably draw like 10 cards because Eidolon of Blossoms also counts as an enchantment for Open the Vaults and if you already had a creature in play then... that's just a lot of card draw. Even if your opponent has no enchantment removal, it will at least bring back a couple Seal of Fires that you might need or maybe one Eidolon of Blossoms that was destroyed.
Idyllic Tutor can also search for your wincon of choice. It might seem lame, but sometimes you will need to use Idyllic Tutor to go get a Sanctum Weaver if you're mana screwed (sometimes from your own Blood Moon lol) or you might also have to go get an Eidolon of Blossoms if the opponent is really heavy on removal and/or you weren't lucky enough to draw one of your creatures that can draw cards. Idyllic Tutor is also really good post board because you can just tutor whatever card you sided in that you know is great in the match up. Absolutely go tutor up that Stony Silence.
I will say that this deck sometimes can feel bad in game one because Ghostly Prison and Blood Moon are useless versus some matchups and you can just get run over by aggro if you don't draw well. I will also say though that if you do win game one, then you probably have got the match in the bag. This deck is very strong with the sideboard.
