Kels origins were in asking, what about a sacrifice commander, someone you can build a pack around? Nocturnal Feeder This workhorse features in all four variants of the Minions packs, a basic card thats there to be sacrificed to enable your more powerful cards, like Kels, while dealing damage to your opponent and restoring your own life
If you cast it at a time a sorcery couldnt be cast, its sacrificed at the end step
Then you can spend 2 mana to exile a card from a graveyard so it's graveyard answers, and if you exiled Dinosaurs you own, you can cast them from exile with a finality counter on them
Anna Braving the Storm gets even more value from your one-drop Heroes and Cinderella Knight in Training facilitates extra cycling
Few things in Magic compare to the feeling of drawing extra cards, letting you grow stronger with every turn
All in all, the perfect general for a budget deck and scary efficient even in normal Commander land
