Consuming Shadow often puts you in a "stuck" state with Orbs where your middle Orbs are Dark Orbs which have scaled lots of damage, but you're always wanting to channel another Orb every turn, and that one gets Evoked by Consuming Shadow, leading to them never making it to the right or left of your Orb Slots to be Evoked. Make sure you have a solution to that if you're taking this card, which is a passable damage card as long as you do!
Evoking your rear orb every turn is meant to allow you to keep a Dark orb in front that steadily grows in power while you play other orb cards. You can also use this to simply activate more Evoke effects. The orb will activate its passive effect on the same turn that it Evokes, so you benefit twice in one turn.
