, Sacrifice an artifact: Bjorna, Nightfall Alchemist deals 1 damage to target creature. Goad that creature. (Until your next turn, that creature attacks each combat if able and attacks a player other than you if able.)
Partner—Friends forever (You can have two commanders if both have this ability.)
Bjorna turns a stream of artifacts into repeatable pings and goad triggers, forcing opponents' creatures to crash into each other while you sit back and develop. You build an artifact engine (Treasure, Clues, tokens) so each turn you can tap Bjorna to weaken a creature and send it at a rival, then close with a goad-based political game or an artifact/spellslinger payoff. With Friends forever you pair Bjorna with a second commander to add a real win engine or extra value.
Repeatable removal-plus-goad that doubles as soft Pacifism every turn
Friends forever lets you bolt on a second commander to cover a win condition
Thrives in artifact-heavy shells that already want Treasure, Clues, and tokens
Strong political control—you turn opponents' boards against each other while staying safe
Cheap two-mana body that comes online immediately
Only one activation per turn unless you add untap effects, so it's slow as a sole engine
Needs a constant supply of expendable artifacts to function
Goad doesn't protect you from spells, ramp, or combo decks that ignore combat
Bjorna himself does little to actually win the game—he's a control/value piece
Vulnerable to artifact hate and to creature decks that can attack you anyway
