Something to keep in mind when resolving multiple cascade triggers is you dont have to cast the spell you reveal
Wizards don't look like printing any new one mana ramp, even in green, and certainly no better than Llanowar Elf
Otherworldly Gaze If you count Surveil spells as self-mill (and I do, given how rarely you see triggers that care exactly how cards end up getting from your library to the graveyard), then Otherworldly Gaze is as good a choice as any for the most consistent, efficient, no-bells-and-whistles version of the effect
