If you don’t want this to happen to you, there’s a way you can save some of your Rats: Figure out which one of your Rats is the target of Bile Blight, and kill it off with some other means (e.g., Ultimate Price or even Devour Flesh targeting yourself) before the spell resolves. When Bile Blight goes to resolve, it’ll find that its target is no longer on the battlefield where it’s expected to be, and the entire spell will be countered for lack of a legal target. None of the spell’s effects will happen, so no Rats will receive -3/-3, and the rest of your swarm will live to annoy your opponent another turn.
