Infinity Formula

The self-attaching entry trigger is the tell of a design built to lower the friction Equipment usually carries. Most equipment sits on the battlefield inert until you pay to strap it on, but this one lands already attached, converting a piece of gear into something closer to an Aura with a second life: knock the creature off and you still have the object, ready to re-equip later. What it buys is modest by intent. A +1/+2 bump keeps a creature alive through more combat math than it deals out, and the lifegain rider triggers on the attack rather than on connect, so the two life is paid the moment you swing regardless of whether the damage lands. That distinction matters more than it reads: it rewards throwing the equipped body into contested combat, since you bank the life whether or not the attacker survives. The whole package points at a straightforward job, propping up a go-wide or lifegain-adjacent creature deck where a durable, mobile buff that pays incremental life is worth more than a bigger one-time swing. It is a workmanlike Equipment: cheap to cast, cheap enough to move around, and content to be the third or fourth piece of a board rather than the centerpiece.
