Here’s a little something to do with your extra copies of Nykthos, Shrine to Nyx copies you have lying around:
1 Temple Garden
2 Stomping Ground
4 Verdant Catacombs
2 Misty Rainforest
1 Kessig Wolf Run
4 Nykthos, Shrine to Nyx
1 Stony Silence
1 Scavenging Ooze
1 Rest in Peace
2 Ghost Quarter
2 Fracturing Gust
2 Courser of Kruphix
1 Ancient Grudge
1 Beast Within
1 Obstinate Baloth
The original list ran 1 x Grafdigger’s Cage, but I opted to run 1 x Beast Within instead (also cage stops your Genesis Wave from putting creatures into play). I also cut a Stony Silence in favor of an Obstinate Baloth. I find it is a rather decent surprise card against non-targeted discard (Liliana of the Veil) as well as being a nice pocket of life for when you are not being the aggressor.
You also get to cast this sweet card. It still looks awesome despite being about 10 + years old.
The deck can have some absurd sequences, such as:
Turn 2: Burning-Tree Emissary, Burning-Tree Emissary, play Nykthos, tap for 5 green mana. Cast Garruk Wildspeaker, untap Nykthos and Utopia Sprawl land, tap Nykthos for 7 (plus the one mana you still have leftover) to cast Primeval Titan or Primal Command (putting one of their lands back on top and getting Eternal Witness maybe?)
Turn 3: Opponent is completely disgusted and is unsure that this even actually turn 3.
Some cards like Wistful Selkie can be Boggart Ram-Gang or Leatherback Baloth if you’re feeling slightly more aggressive, but I prefer the cantrip and they both pretty much contribute the same towards devotion. Having only run the deck once, I can’t really say that Selkie is the right card here. I also adore Eternal Witness in this particular deck since it does a lot for it. It can even do ‘unimpressive’ things like grab back a fetchland if you haven’t accelerated at all, so that you can cast your turn 4 Garruk Wildspeaker. The deck also features another card that’s been slightly underplayed in Modern thus far:
Remember this guy ?
Playing Nykthos Green will oftentimes feel like you are playing a game of Commander (minus Primeval Titan, since he’s banned). It’s actually one of the more reasonably priced Modern decks out there ( you don’t ‘have’ to run the fetches) and its cost to fun ratio is pretty great. Give it a try, you won’t regret it.
Warning: Casting Primal Command versus mill decks might cause opponents to rage quit.
