Ravaging Blaze

The clever part is that the growth clause and the reach clause share a single X, so filling your graveyard doesn't add a second target: it makes the one you already picked hurt twice. Early, the frame buys plain creature removal: pay X, drop a blocker or a threat. Later, once two instants or sorceries have piled up in your yard, the identical X splashes off the creature and onto its controller, converting a removal spell into reach you can point at the dome. Spell mastery is elegant here because it asks nothing a spell-heavy deck wasn't already doing; the payoff accrues passively as the game runs long rather than demanding a dedicated enabler slot. That is the quiet virtue of the mechanic: it rewards the archetype's natural behavior instead of a card spent priming it. The double red keeps the removal side honest, ensuring real color commitment even at the floor, while the upside is tuned for exactly the deck that wants its burn aimed at a face anyway. Every additional mana you sink scales both halves of the same number at once, so the ceiling climbs with whatever mana you can pour in past that red requirement rather than capping at a fixed figure. The result is conditional design where the floor is serviceable removal and the ceiling is a game-ending burn to the face, with the distance between them measured entirely by your own graveyard.
