How about some more intensity?

Kid Icarus: Uprising's intriguing Fiend's Cauldron mode is the subject of this new trailer.

The Fiend's Cauldron lets you bet previously acquired hearts to ramp up the intensity of levels; the more hearts you bet and the more difficult the stage, the higher the reward.

The video makes it all pretty clear, so have a look and buckle down for Uprising's March launch.
