I've always been a Golgari player and while everyone is frantically Googling Tarkir spoilers, I feel now is the time to get this deck off the ground.
There is SOOO much hate that rotates out in a few weeks, but with this deck you can keep slapping down the cards and living it up well into next year. Obviously time will tell but give it a chance!
Basically, this is my take on a post-rotation Constellation deck that I've been refining over the months and has proven pretty effective to date on MTGO. It's probably not gonna be winning any PT's anytime soon but when it works, it's hella fun to play and the strategy is simple to understand (but though to master...)
The deck is all about Constellation synergy. It's primarily based around abusing Eidolon of Blossoms as a card-draw engine and tripping as many Constellation triggers as possible. If you're playing it right, everything should be drawing you cards, gaining you life or killing an opponent.
The majority of the creatures are there to trigger Blossom until you have an effective board and can start making way with Fate Unraveler, Boon Satyr, Nissa, Worldwaker and the Gods.
Sequencing is VERY important to ensure triggers from Courser of Kruphix, Pharika, God of Affliction and Grim Guardian are hit in the right order. There's a lot of Scying and card-draw and graveyard-interaction here so take your time!
Anyway, let me know what you think!
