Firstly, as defense is a weakness of monogreen, this deck aims to start with a solid defense; hopefully wielding some power similar to the white, but without straying from monogreen. That is the place of Fog, Dense Foliage, Moment’s Peace, Asceticism, Tangle, Ground Seal, Gaea’s Herald, and defender creatures like Traproot Kami, Shield Sphere, Steel Wall, Wall of Tanglecord, Wall ofVines, Carven Caryatid, Wall of Brambles, Mitotic Slime, and Master of the Wild Hunt as well as Glissa Sunseeker to take care of oodles of artifacts. Also, Not of this World is a great way of saving this massive hungry creature deck.
Two cards in this deck are essential Norwood Priestess, and Elvish Piper. There are plenty of ways to fetch them, like Elvish Harbinger, Fauna Shaman, Green Sun’s Zenith, Wirewood Herald, Skyshroud Poacher, Worldly Tutor, or to bring them back to life, like Genesis, Revive, Evolution Charm, Wildwood Rebirth, Wrap in Vigor. However, they aren’t so essential that the entire deck will fail without them. For example, AEther Vial, Quicksilver Amulet, Natural Order, Cryptic Gateway, Dramatic Entrance, Pattern of Rebirth, Tooth and Nail, and Defense of the Heart are other ways to bring out the bad boys.
I should also mention the fun can really roll by equipping Silvos, or other beatsticks with Fireshrieker, Whispersilk Cloak, Swiftfoot Boots, and/or Trailblazer’s Boots.
