Relentless Rohirrim

A 4/3 for four in red is a body priced for pressure, not one you build around, and the enter trigger here does something quieter than the Ring temptation usually implies. Most cards that tempt the Ring on entry are cheap and expendable, meant to feed the Ring-bearer through as many chapters as possible for the incidental value. Stapling that trigger to a midsized aggressive creature reframes it: this is a beater that also advances your Ring's escalation, so the temptation reads less like a bonus and more like the tax attached to a slightly-below-rate attacker. The four levels ramp through evasion for whichever creature currently bears the Ring, then a draw-and-discard, then forcing the opponent to sacrifice a blocker at end of combat, and finally life loss whenever the bearer connects. That escalation rewards decks already committed to the mechanic, where every fresh temptation pushes the ladder further rather than resetting it. And because the Ring lets you name a new bearer each time it tempts, the trigger is a reassignment tool as much as a counter, moving the escalating buffs onto whatever creature is best positioned to swing this turn. On its own it tempts once and moves on; in a shell built to keep tempting, it is one more turn of the ratchet.
