Strata Scythe

The buff scales with a number you control by building toward it: imprint a land you run many copies of, and the +1/+1 stacks once per matching land on the battlefield, counting everyone's lands, not just yours. In a heavy mono-color deck full of one basic, the equipped creature swells with the board state itself, and every land you draw and play after is another point of power waiting in your hand. The structural quirk is that the count is purely name-based, so the imprinted card matters less than the lands already deployed; a deck running fifteen Snow-Covered Mountains turns this into a runaway threat, while a fixing-heavy build gets a marginal bonus and little else. That ties the Equipment's ceiling to manabase homogeneity in a way most pump effects never have to think about, rewarding the kind of land-flooded mono-color shell that would otherwise drown in its own draws. It punishes diversity rather than encouraging it: the more colors and the more unique lands you play, the smaller the buff, so the card reads as a deliberate payoff for committing to a single basic and running an unusual density of it. The imprint also acts as a small thinning effect on the way in, pulling one land out of the library, but the search is for any land card, leaving room to grab a nonbasic when the buff is incidental and a fetchable basic when it is the point.
