Lich + Aetherflux Reservoir?

Why isn't this in any grixis storm deck like Jeleva? Sure, 4 black mana is pretty intensive but resolving this wins you the game so easily. Lich and Ad Nauseam also draws your deck in grixis colors. Aetherflux and Lich allows you to never brick again, drawing a card for each life which continually goes up until you cast Lab Man and draw your deck winning the game. Tendrils of Agony for even like 5 or 6 which is easy, draws you 10 to 12 cards, more than enough to win. Maybe not tier 1 or anything but it seems easy enough to get online in a all-in storm deck. ...Thoughts?
