Balduvian Shaman

Tap a 1/1 and you become a continuity editor for your own white enchantments, swapping one color word inside their text for another. The ability presumes a very specific board state: the color-hosing static effects of early design, the Karma- and Justice-style permanents that punish or restrict a named color. This shaman lets you point those static guns somewhere new mid-game, turning an enchantment aimed at one opponent's deck into pressure on another. The cost is the interesting part, because the rewrite is not free: the target picks up cumulative upkeep, so every enchantment you edit starts accumulating age counters and demanding escalating mana, eventually folding under its own rent unless you keep feeding it. That self-imposed clock is the only thing keeping the flexibility in check, and the requirement that the target not already carry cumulative upkeep prevents you from stacking the effect on a single permanent over and over. The result is a fossil of how text manipulation was once handled at the rules level: not as a templated keyword but as a literal find-and-replace instruction, paid for with a ticking sacrifice timer. Very little since has paired color-word substitution with a built-in expiration date in one tap, leaving this closer to a logic puzzle than a creature.
