I’ve been playing MtG for a long time now, and as of late, I only play and follow Legacy, Vintage, and EDH formats. The following is a few selected decklists that I created and have played with. You’ll find detailed descriptions of each in the accompanying links. They’re ordered by popularity.
GW Cataclysm loam
A mid-range deck that resembles Maverik but uses Cataclysm for board control and Life from the Loam + Scroll Rack as card advantage engine. (Legacy)
Deadguy Ale - Land Tax variation
A variation of Deadguy Ale (Aggro-Tempo) that brings a Land Tax package to add an alternative win-con (Zombie Infestation) and card-advantage engine (Scroll Rack) to the already tried-and-tested core-list. (Legacy)
Rubinia Old School (Pre-Tempest)
A casual Rubinia (Bant) Control deck that has two noteworthy restrictions: (1) It only includes cards originally printed before the Tempest block (until mid-97); (2) It follows the current EDH banned list. (Multiplayer EDH - Pre-Tempest variant)
