I’m pretty sure Jason’s only been reading comics since maybe 1998 or so, because there’s plenty of other good storylines to be mined, going back quite a ways.
— Ragnorak & Roll (Avengers 300 or so, crossed over w/ Thor and others)
— Secret Wars (already mentioned elsewhere, but unlikely b/c of XMen)
— Lost in Space-Time (West Coast Avengers circa 1987)
— Any Damage Control series, ever
