Inherited Envelope

Manalith set the baseline: three mana, enters untapped, taps for any color, no strings. Every any-color rock at this price is measured against it, and most that try to improve on the rate pay for the upgrade with a comes-into-play-tapped clause, a life tax, or a body that makes it a creature vulnerable to removal. This one takes the opposite approach: it keeps the clean, untaxed Manalith mana ability intact and staples a benefit on top. The moment it lands, the Ring tempts you, which means your first Ring-bearer designation and the whole escalating emblem come free with your ramp, no legendary creature or dedicated payoff required to unlock the sequence. That is the wrinkle worth sitting with. Fixing is normally a decision made in isolation, a card you play to smooth the next few turns and then forget about. This one entangles your mana base with a mechanic that keeps compounding: each subsequent trigger climbs the Ring's ladder, so a rock you cast on turn three is quietly banking toward better combat math and card advantage later. The temptation is not a cost the card pays to justify its rate; it is the upside a plain rock cannot match in any deck already leaning on the Ring. A mana source that also advances a subplot, at no premium over the vanilla version.
