Jadelight Spelunker

Explore has always been a mechanic that scales with quantity: one trigger is a coin-flip between a land and a growth counter, but stacking them turns variance into a curve you can bank on. This is the card built to abuse exactly that, folding the count directly into the mana cost so every extra mana buys another reveal off your deck. The genius of the X-times structure is how it launders green's oldest tension between size and card advantage: each explore either digs toward a land you keep or leaves a body that grew, so there is no dead outcome, only a spectrum from fatter creature to filled hand. Cast small on an early turn and it is a modest scout that smooths a draw; cast it as a late-game payoff and it arrives as a self-milling, hand-refilling threat whose final toughness you cannot fully predict but can reliably expect to be large. The graveyard clause matters more than it looks: the choice to bin a revealed nonland rather than replace it feeds any strategy that wants cards in the yard, quietly making this a delve enabler and a reanimation setup on top of a growth engine. It is the rare curve-topper that is also a curve-filler, a single card that answers "what do I do with my extra mana" at nearly any point in a game.
