Glamdring (Roto/Sealed Cube)
This cube seeks to exploit the unique design space afforded by Rotisserie Draft, Sealed, and similar formats. Therefore it includes a high density of "quality of life cards" like Lessons, 1-mana Cycling, MDFC lands, and other smoothing effects. Additionally, to provide many divergent paths, it seeks for a high power delta and a lot of build-arounds that radically recontextualize the draft -- Companions being just one example.
