Ghave, Guru of Spores (Melira Combo) Glissa, the Traitor (undying artifacts!) Previous Commander decks currently on hiatus : Grimgrin, Corpse-Born (Necrotic Ooze Combo) Damia, Sage of Stone (Ice Cauldron shenanigans) Geist of Saint Traft (Voltron-ish) Glissa Sunseeker (death to artifacts!) Jor Kadeen, the Prevailer (replacing Brion Stoutarm in Mo Myrs) Thelon of Havenwood (Campfire Spores) Melira, Sylvok Outcast (combo killa) Konda, Lord of Eiganjo (The Indestructibles) Vorosh, the Hunter (proliferaTION) Progenitus (Fist of Suns and Bringers) Savra, Queen of the Golgari (Demons) Uril, the Miststalker (my "more competitive" deck)
