I ran supreme blue as well last sunday at a 24 man tourney and did pretty well (3rd) going 4-1-0. The loss was to landstill, and man was it complete. Vendillion clique helps a ton in the control matchups, as well as running more red elemental blasts. Other than that, I too am looking for ways to improve on my poor matchups and would be interested in hearing what others are doing.
