This deck aims to get a bunch of creatures in the grave and win with Strength from the Fallen.
Riptide Chimera can bounce cheap enchantments, hopefully making it easier to trigger constellation. Strength from the Fallen will usually target my 3/4 shark birds because of their evasion. Also... 3/4 enchantment creature with flying for 3? With an ability that helps my deck more than hinders it? Sign me up. Can't even Lightning Strike these bad boys. He bounces Strength from the Fallen to ensure I'm always hitting my constellation triggers... Sweet! I can easily swing for 9 or 10 with this guy.
Kruphix's Insight and Commune with the Gods are essential to the deck, it's pretty much the only way I'm dumping things into the graveyard. It's nice, because technically I don't need to put any cards in my hand with either of these spells if I'd rather feed my graveyard.
Between Courser of Kruphix, Eidolon of Blossoms, Polukranos, World Eater, etc, this deck generates loads of devotion to green. Nykthos, Shrine to Nyx + Voyaging Satyr finds a nice home in this deck.
You may think Nykthos x3 is a bad idea, but it isn't necessarily a dead draw if I have it on the battlefield already. I can tap it, get devotion off of it, play a new one, kill the old one with the legendary rule, and have an untapped Nykthos, Shrine to Nyx to get devotion off of all over again. This often yields more mana than playing a basic.
This combo paired with the Sylvan Caryatid and Courser of Kruphix makes this deck really rampy, which is nice for costlier spells. Also the caryatid and courser are awesome blockers. A lot of the time it's fine to block with them, even if they die to enable Strength from the Fallen.
In case my flying shark abominations don't do the trick, or aren't getting through, Polukranos, World Eater is a nice alternative win condition. With all the devotion, the Nykthos, Shrine to Nyx + Voyaging Satyr combo can sometimes clear the entire board when paired with Polukranos. I got 21 mana in one turn the other day... He certainly does eat worlds. Make this guy huge, kill their stuff, and swing in for lethal, hopefully!
Nylea, God of the Hunt is a good "just in case" card. She's giving all my guys trample in case I can't get through their blockers, and she's almost always gonna be a creature.
Primeval Bounty is also great here. It counts for constellation, and makes my board big... and if I bounce Strength of the Fallen with the shark bird and it play it back, I'm getting the buff from constellation as well as three counters.
Arbiter of the Ideal is a lot of fun. Not sure if I should main board her, but almost all of the cards in my deck are permanents, so it seems suitable. Swing for 4 or more in the air, untap next turn, get a free spell or land, trigger constellation. Cool.
I need to pick up more non-basics, and my second Primeval Bounty and Eidolon of Blossoms for this deck, they're pretty key cards.
Feedback appreciated! Thanks for reading guys! :)
