Whenever you attack, you may sacrifice another creature or an artifact. If you do, create a 4/1 black Skeleton creature token with menace that's tapped and attacking. (It can't be blocked except by two or more creatures.)
Choose a Background (You can have a Background as a second commander.)
Attack each turn, sacrificing a cheap creature or expendable artifact to immediately deploy a 4/1 menace Skeleton that's already tapped and attacking—converting fodder into evasive damage. You flood the board with token generators and treasure/artifact creatures, then leverage sacrifice triggers (Mayhem Devil, blood artists) for extra value while the Skeletons chip away. With a Background, you fill out the second color or buff your aggression to close fast.
Turns chump tokens and dead artifacts into 4-power evasive attackers for free every combat
Strong synergy with aristocrats payoffs—every attack is also a sacrifice trigger
Cheap 3-mana commander that pressures from early turns and rebuilds quickly
Background slot lets you customize toward go-wide, sacrifice value, or extra colors
Skeletons are 4/1, so they die to any chip damage, pings, or board wipes easily
Needs a steady stream of sacrifice fodder—runs dry without token engines
Mono-red (without Background) lacks card draw and interaction depth
Heavily reliant on attacking, so Fog effects, big blockers, and stax slow it considerably
No built-in protection; removing Gut shuts off the Skeleton engine
