What it does
Coruscating Flames isn't actually a keyword ability—it's an individual card (a sorcery from the Onslaught block era). It deals 4 damage to any target (creature or player), and crucially, that damage can't be prevented. It's a straightforward red burn spell with a built-in answer to damage-prevention shields like protection-style effects or fog-type abstractions, though note "can't be prevented" doesn't bypass everything.
The common misunderstanding: "can't be prevented" only stops prevention effects, not redirection, replacement, or other interactions. It won't punch through indestructibility (that's destruction, not damage prevention), won't ignore damage being redirected, and a creature with toughness above 4 still survives. Hexproof or shroud still stop you from targeting it entirely.
In Commander, it's a niche flex slot—4 damage matters less in a 40-life format, so it sees little play outside dedicated burn or unprevention-themed decks.
