Knight of the Reliquary

Sacrifice a Forest or Plains to fetch any land and you have spent no net mana: the count of lands in play stays even, but you trade a land you no longer need for whatever the deck actually wants, basic or nonbasic, since a shockland or dual carrying those land types is fair game too. The payoff is the body. Every sacrificed land goes to the graveyard, every land in the graveyard feeds the static buff, and so each tap that fixes your mana also grows the threat: a 2/2 that compounds itself one activation at a time, with the pilot choosing when and how much. That self-directed loop is what separated it from the era's other green-white beaters, which sized off counts the pilot did not control. Here you choose the inputs, and a recurred fetchland turns the engine into a graveyard sink that buries more lands with each pass. Timing is the other half of the appeal. Hold a fetchland and you can crack it in response to removal, padding the graveyard at instant speed and shrinking the window an opponent has to kill it on its printed stats. At three mana it arrives as a midrange threat rather than a finisher, but in a deck built to fill its own graveyard, it becomes a clock that climbs every time the mana does.
