This W/G Constellation deck has 27 enchantments, 12 of which being creatures. This midrange deck is dominate and can take over games quickly. It can beat Aggro decks with no problem and can easily beat control after sideboard. Mana is really great I rarely have problems with mana. Even with the double devotion of Courser of Kruphix and Sigil of the Empty Throne. An optimal start would be a turn 2 Herald of the Pantheon and on turn 3 playing Frontier Siege(choosing khans) and on you're next end step playing Courser of Kruphix.
Creatures
Nyx-Fleece Ram is a 0/5 2 drop that can cause troubles for Aggro decks gaining you life and being out of range for normal burn spells.
Herald of the Pantheon is a 2/2 2 drop that can make all of your 27 enchantments cheaper. It allows you to ramp up and beat the Aggro decks while also gaining you life.
Courser of Kruphix is a strong 2/4 3 drop. Courser's ability allows you to dig through your deck for lands and gains you life at the same time. As you can see there is a lot of life gain in this deck.
Eidolon of Blossoms is a weak 2/2 4 drop, but don't under estimate this card. Everytime you play an enchantment with this creature in play you draw another card. This allows you to dig through your deck very quickly. The only downside to this card is you can mill yourself which I have done so be careful and play smart.
Rest of enchantments
Starfield of Nyx is a very powerful card in this deck. Its a 5 drop but it is worth the mana. Every upkeep you are able to bring back an enchantment from the graveyard and put it on the battlefield. If someone destroys you're Banishing Light, bring it back. If someone destroys you're Courser or Ram, bring them back. And don't forget once you get 5 enchantments on the battlefield all your enchantments become creatures.
Sigil of the Empty Throne is also a 5 drop, but it too is powerful. Everytime you play an enchantment you get a 4/4 angel and you're almost always going to be playing at least one enchantment per turn. The double white can be a problem, but usually works all right.
Frontier Siege is a 4 drop that allows you to play a 4 drop and a 3 drop the next turn. It is great for ramping and its dragons abiltiy can be relevant with Sigil of the Empty Throne
Silkwrap
is a great card for removal. It crushes rabblemasters, Coursers, Fiendslayer Paladin, Loxidon Smiters, Boros Reckoners you name it! And its only for 2 mana.
Banishing Light does the same thing as
Silkwrap
except it can take out anything except for lands. For 3 mana you can exile anything you don't want to deal with.
Now for the 1 sorcery in the deck,
Kruphix's Insight
. This card allows you to search for enchantments you need if you can't seem to draw them. With 27 enchantments in the deck you rarely bust with this spell.
Sideboard
Boon Satyr
is a powerful 4/2 3 drop with flash. It comes in against certain Aggro and control match ups
Nissa, Worldwaker comes in against control decks. She enables you to untap 4 lands to cast more spells, but the main reason to play her is to put pressure on your opponent with 4/4s
Rest in Peace comes in against any deck using their graveyard. Say goodbye to Tarmogoyf, Tasigur, Dig Through Time. Delver and dredge decks have nothing on this card.
Sigil of the Empty Throne comes in against control for the same reason as Nissa, Worldwaker.
Stony Silence is for the affinity match ups or decks with a lot of artifacts.
Suspension Field is for creature oriented decks or decks with big strong creatures.
Well that's my deck if you like it leave a +1. Also free free to leave suggestions. I love to hear feedback.
