Wreck and Rebuild

Two Gruul staples fused into one modal slot, and the seam is what the design is about. Naturalize has always been the tax you pay for maindeck answers to artifacts and enchantments: dead against decks that run neither, live only when the board hands you a target. Milling five and returning a land from the yard is the opposite kind of card, a proactive ramp-and-fill play that never sits idle in hand. Stapling them together lets the same card flex between the two roles depending on what the game asks for: destruction when there is something to destroy, self-mill acceleration when there is not. Flashback keeps the modal choice from feeling like a one-shot compromise. The graveyard mode digs toward the land you need and stocks the yard for the second cast, so the two halves feed each other: mill early to fuel the ramp, then flash it back later as removal once an artifact or enchantment finally shows up. That loop is the reason this reads less like filler modal fixing and more like a deliberate engine piece for a deck built to grind through its own library.
