My take on a modern green devotion deck. The main object is to be able to play your entire deck, at around turn 4-6.
The cards:
Mana: The initial mana suppliers.
Arbor Elf: Mana acceleration. Combos with Utopia Sprawl.
Voyaging Satyr: An Arbor Elf that also untaps Nykthos, Shrine to Nyx.
Utopia Sprawl: Mana acceleration. Use Arbor Elf and/or Voyaging Satyr to untap the enchanted Forest for extra mana.
Devotion Mana: Build up a large devotion to green and produce large amounts of mana.
Karametra's Acolyte: Produces lots of mana with devotion from everything else you play.
Nykthos, Shrine to Nyx: Like Karametra's Acolyte, but a land.
Burning-Tree Emissary: Gives you 2 devotion, and can pay for something else.
Elvish Visionary: 1 devotion and cantrip, which is really helpful.
Wistful Selkie: 3 devotion, and also cantrip.
Big card engines: Use the large amount of devotion mana to draw and play most of your deck.
Regal Force: Draws lots of cards, provides 3 devotion, and is a 5/5. You'll often draw into more card engines, and have enough mana to cast them in the same turn.
Genesis Wave: Use all the mana you produce to make a massive Genesis Wave and play a large chunk of your deck.
Garruk, Caller of Beasts: Draw up to 5 creatures a turn. It's likely you'll get a Regal Force and draw even more cards. Typically, the -3 isn't used often, and you almost never reach or need the ultimate.
Staff of Domination: Gives infinite mana, life, creature tapping and untapping, and cards. This goes infinite with Karametra's Acolyte and 5 devotion or Voyaging Satyr, Nykthos, Shrine to Nyx, and 7 devotion.
Finishers: What kills and helps to kill your opponent.
Primalcrux: With everything out on the battlefield, these will be about 50/50s.
Akroma's Memorial: Gives your Primalcrux and all your smaller creatures tons of abilities
Sideboard: Needs help. This deck is not made irl, and I don't play competitively, so I have no idea what the metagame is like.
Beast Within: Creature removal.
Creeping Corrosion: For Affinity or any other artifact strategy.
Ground Seal For graveyard strategies.
Melira, Sylvan Outcast: For infect.
Nature's Claim Artifact and enchantment removal.
Vexing Shusher: To avoid countering.
Please comment any suggestions, thank you!
