Commander is where Rune of Sustenance earns its reputation: Aura-matters commanders treat it as an unconditional one-mana cantrip that leaves a lifelink buff behind, which is a clean rate in a format full of battlefield-centric engines. Outside Commander, the card is legal in Legacy, Modern, and Pioneer, but those formats have no interest — enchantment-based lifegain strategies don't exist at competitive levels there, and a one-mana Aura that draws a card isn't powerful enough to slot into any other shell. Oathbreaker mirrors Commander's logic, so the same Aura-matters or lifegain planeswalker builds that want it in Commander want it there too.
