Warning is a one-mana instant that prevents all damage from a single source, giving you a hard stop on any combat strike or direct damage effect at the lowest possible cost. It's narrower than Fog effects but cheaper, and in the right shell that trade-off is correct.

In Commander, Warning slots into decks that need cheap, reactive protection on a budget — it answers a single threat rather than the board, so it earns its slot primarily in spell-slinger or spellcount-matters builds where every one-mana instant has double duty. In Legacy and Vintage, dedicated damage-prevention strategies are too slow and too narrow to compete, so Warning sits on the shelf there. Pauper is its most credible competitive home: one-mana interaction is at a premium in the format, and stopping a pumped attacker or a burn spell for a single white mana is a real rate.

Price Context
Current price
$0.09 bulk tier
At $0.09, Warning is deep bulk — a card you pick up by the handful out of a commons box without thinking twice. Don't expect that to move; there's no scarcity story here, just a cheap effect available to anyone who wants it.
