Conviction

Most toughness-pumping Auras are a losing trade, and everybody who has played with them knows the shape of the loss: you spend a card to save a creature, your opponent points removal at the host, and both go to the graveyard for a single spell. The recurring return clause is the answer to that math. Pay one white mana and the Aura comes home before the punishment lands, ready to redeploy next turn on whatever needs the bump. That turns a committed card into a reusable resource. The +1/+3 split is weighted toward survival rather than offense: this is built to keep a blocker standing across multiple turns and to win combat-math problems, not to push damage through. The mana tax is the design discipline that keeps the loop honest, since each escape costs a white mana you might rather spend elsewhere, and the protection is only as good as your willingness to keep paying it. The instinct here is the same one buyback and flash-bounce effects would later formalize: an Aura that refuses to be a one-for-one because it is always willing to leave the battlefield on its own terms.
