Swirl the Mists

Color words live in a strange corner of the rules: text like "white creatures" or "deals damage to a black or red permanent" is parsed as a literal string, not as a property the engine derives. This enchantment seizes that string and rewrites it everywhere at once, on every spell and permanent, present and future. The result is a board where one chosen color word is the only color word that exists. Protection from white becomes protection from your chosen color; Pyroclasm-style "white or green" clauses collapse to a single word; a Circle of Protection's instruction now reads against a color it was never written for. The design is a puzzle box rather than a power card: its whole effect is invisible until you find spells whose text happens to name colors, then bend that naming to your favor. That makes it one of the purer expressions of the "wordplay" design space Magic flirted with in its early years, where text was treated as raw material to be edited rather than rules to be obeyed. It shares lineage with cards that swap creature types or basic land types wholesale, the same trick applied to a different category of word. The cost reflects that it does nothing on a typical board; it is a setup piece for decks built specifically around protection clauses, color-hosing effects, and the seams where the comprehensive rules treat language as data.
