Ring of Renewal

Five mana to cast, five more plus a tap to activate, and even then the engine takes a bite out of you before it pays: the discard is random, and it happens before you see the two cards you draw. That ordering is the whole personality of the design. You cannot dump a dead card on purpose, cannot hold information back, cannot sculpt your hand. You feed the machine blind and accept whatever it returns. The net is a single card gained per activation at a price steep enough that the artifact functioned only as a slow long-game grind and never as a tempo play. It belongs to an era when raw, repeatable card draw was treated as inherently dangerous and therefore taxed into near-immobility, before the mechanic learned to filter cleanly with loot effects that let the controller choose the discard, and before card advantage at this price point became routine. What it represents is the cost of that caution: a draw engine balanced so heavily against its own user that the random discard reads less like a drawback and more like an apology for letting the artifact exist at all.
