My buddy Mike Vasovski made the Canadian National Team many moons ago with this Simic special: "Simic Special" Creatures (20) 3 Ninja of the Deep Hours 3 Patagia Viper 4 Coiling Oracle 4 Sakura-Tribe Elder 4 Sakura-Tribe Scout 2 Seshiro the Anointed Spells (18) 2 Chord of Calling 3 Mana Leak 3 Remand 4 Sosuke's Summons 3 Coat of Arms 3 Umezawa's Jitte Lands (22) 3 Island 7 Forest 4 Breeding Pool 4 Simic Growth Chamber 4 Yavimaya Coast Sideboard (15) 2 Ghost Quarter 3 Gifts Ungiven 1 Life from the Loam 3 Pithing Needle 3 Spell Snare 3 Threads of Disloyalty Beyond the tribal synergies, Coiling Oracle did a lot of work in this deck, from accelerating the mana (revealing Simic Growth Chamber is pretty dirty) to helping power out a Chord of Calling to being best friends with Ninja of the Deep Hours
