Turf War

Land control is one of the least-touched axes in Magic: for all the color-pie effort spent on stealing creatures and borrowing artifacts, permanent land theft has stayed rare, precisely because taking a player's mana permanently distorts a game faster than any single threat. This design threads that needle by making the theft conditional and reciprocal. Every player at the table starts with a single contested land, so nobody is singled out; the counter just sits there, marking territory, until combat converts it. The clever piece is the trigger's wording: it is the defending player's lands that matter, and the attacking creature's controller who claims one. That turns each contested counter into a bounty on connecting damage. Because the trigger fires per creature that deals combat damage to a player, the marked land does not change hands until someone actually gets hit; a player who leaves themselves open to an attacker hands a piece of their mana base to whoever swings through. With one contested counter apiece, the pressure stays measured rather than snowballing out of a single unfortunate hit. The result is a Group Slug piece that deals no damage itself yet rewards aggression, redistributing mana toward the players who can force damage through rather than the ones who can absorb it. The untap clause is the detail that raises the stakes past pure symbolism: a stolen land arrives ready to use, so the swing is not just denial but immediate acceleration for the aggressor.
