Averna, the Chaos Bloom
Cascade throws away as much as it finds. You flip through your library until you hit something cheaper, and everything above it, lands very much included, gets buried on the bottom of your library in a random order with nothing to show for it. This card converts that waste into ramp: the land you would otherwise have shuffled to the bottom enters the battlefield tapped instead, and the timing clause is the whole engine. It resolves after the last card is exiled but before you decide whether to cast the nonland card underneath, which means a single cascade trigger banks a land and still sets up the free spell in one motion. Stack multiple cascade sources and the effect compounds; every trigger is another chance to salvage a land from the pile that would have vanished under the deck. The color combination is the real payload, since it turns on cascade cards printed across three colors rather than one. The 4/2 body is beside the point. The design reads less like a creature than a rules amendment: it takes cascade's most frustrating downside (the fistful of exiled cards you never see again) and quietly reroutes one of them into board development. Building a card around patching a mechanic's fine print, rather than around a combat ability or a damage trigger, is the rarer and more interesting design instinct.
