Sagas

MTG Mechanic

Every Saga has three chapters, represented by the I, II, and III symbols. Each chapter also has a corresponding effect. For The Flame of Keld, we see that the effect of chapter I is "Discard your hand." The story gets better, I promise. Some Sagas have the same effect for multiple chapters. Instead of that effect being listed more than once, you'll notice that the chapter symbols are just grouped together with the appropriate effect.
