This clever loop sets up an infinite recursive engine by leveraging the legend rule alongside continuous trigger generation. When you cast Carnage, Crimson Chaos, its enter-the-battlefield ability plucks Deceptive Frostkite straight out of your graveyard, allowing it to enter as a copy of Carnage. Because you now control two legendary creatures with the same name, the state-based legend rule immediately sends the copy to the graveyard—which cleverly triggers its own entry ability all over again to resurrect itself as Carnage once more. This seamless self-sustaining cycle generates infinite enters-the-battlefield triggers, leaves-the-battlefield triggers, and death triggers to fuel whatever payoff you have waiting.
