Elixir

The healing consumable of a hundred JRPG battles, translated into an artifact whose entire job is a graveyard reset with a life-total kicker. The cost structure tells you exactly what kind of card this is: one mana to deploy, but it enters tapped and demands five more mana plus the tap to fire, so it is never a same-turn play and never a cheap trigger. That heavy back-end price frames the effect as an inevitability rather than a value spell. Anti-mill and anti-decking is the obvious use, since shuffling every nonland card back in refills a library that was about to run dry, but the life gain scales with exactly the cards you are recycling: dump a full graveyard back into your deck and the total climbs to match. The wrinkle worth tracking is that it is one-shot, exiling itself as part of the activation cost, so there is no repeatable loop here, just a single large reset once you can afford six total mana and a tap. That makes it a patient card, one that sits on the battlefield as the threat of a reset rather than an immediate answer, and one built to blunt strategies that grind you out of cards over a long game rather than beat you fast.
