Chokeutility$1.20A classic color-hoser that punishes a dominant basic land type by shutting down Islands instead of destroying them. It fills the same sideboard role as Boil against blue-based decks.
Boiling Seasutility$2.34Very close functional equivalent: it is another red spell that directly destroys all Islands. It overlaps heavily in role and mana cost, making it the most on-theme substitute.
Flashfiresutility$0.16Similar hate card that wipes out a specific basic land type, but targets Plains rather than Islands. It serves the same anti-color sideboard function in red.
Tsunamiutility$46.24A red mass land hate spell aimed at Islands, with a very similar game plan to Boil. It is one of the closest functional matches, though its exact text differs by version.
Back to Basicsutility$3.56Not red, but it serves the same strategic purpose of punishing nonbasic-heavy or blue control mana bases by making Islands and other lands much less effective. It is a strong functional analogue in eternal formats.
Blood Moonutility$8.90Another premier land-hate piece that attacks blue mana bases by converting nonbasics into Mountains, often locking out Islands indirectly. It is a broader and more powerful substitute in many formats.
Price of Gloryutility$10.86This does not destroy Islands, but it punishes blue decks for playing on opponents' turns and is often used in similar anti-control sideboard plans. It fits the same anti-blue game plan rather than the exact land destruction text.
Ruinationutility$0.74A red mass land-destruction spell that can devastate Island-heavy manabases by hitting nonbasic lands broadly. It is a stronger but less targeted option for the same kind of mana denial role.
