i'd say magic died in 2020 with the introduction of fire and secret lair. each set after eldraine has been progressively shittier and more pushed, modern horizons has rotated modern and turned it in to a joke format so much premodern became a thing, wotc tested ub in standard with dnd (no one understood it) and the competitive scene died with coroners

if only we knew oko/omnath and the walking dead were just the tip of the iceberg, 2020 truly is the year mtg died
