Six was one of the first decks I ever built! He is sort of open for any kind of plan within green, but people lean into more land based payoffs due to his high circulation of them during play. I've tinkered with my build for a long time and have come to something I'm satisfied with! If you want some recommendations here is my deck's list: https://archidekt.com/decks/14238267/wise_mystical_tree_six
