Bilbo, Retired Burglar

The Ring temptation stapled to both entering and leaving is the whole trick, and it turns a punishment into a payout. Most Ring-tempts creatures hand you one escalation and stop; this Halfling gives you a second tempt every time it exits the battlefield, so blink effects, bounce, and sacrifice-and-recur all push the Ring forward rather than resetting it. The temptation itself is what pairs the body with its role: as the Ring's tiers accrue, the small frame gains evasion and combat reliability, and the combat-damage Treasure trigger converts each connection into ramp for the next spell. The 1/3 is the constraint that keeps this honest. It is a bearer, not a threat, so the value it generates has to be spent quickly before an opponent decides a 1/3 hauling a Treasure is worth trading down for. What makes the design read as characterful rather than generic is the shape of the loop it wants: not a single big swing but repeated small ones, a burglar slipping in and out, each pass leaving something behind and edging the temptation forward. Blue-red usually buys its value with spells; here it comes from an evasive creature that treats the Ring's escalating menace as a fuel line.
