Grimgrin - Infinite Zombo Deck

This is a mid-speed Dimir zombie sacrifice deck that builds mana and board presence through the early turns, then looks to close around turn six with engineered loops. It plays as upgraded bracket-three combo-midrange: interactive enough to disrupt, dense enough to assemble wins in the midgame without pure cEDH velocity. Expect a fair tribal shell that can suddenly end the table once its engines connect.
