Sefris, Dungeon Speed-Runner v1.1.MKM (EDH / Commander) [Revisione 12]

'Sefris of the Hidden Ways' powers a creature heavy, recurring ETB/LTB and Dungeon pay-off value engine. While this build is equipped to protect Sefris, the value competes on it's own and 'Radiant Solar' makes a capable lieutenant. While all +/- 40 creatures are selected for utility, many provide multiple pay-offs. Plague Wind provides a final haymaker.
