Goblin Cratermaker

Red has burned artifacts since the beginning: Shatter and its descendants are as old as the game. What makes the sacrifice ability here worth the slot twice over is that its destruction mode reads wider than "artifact." Colorless nonland permanent catches Eldrazi, manifested or transformed colorless threats, the odd colorless enchantment or planeswalker, and yes, artifacts along for the ride. The fence is that "nonland" clause: colorless creature-lands and their kin stay out of reach, because a land is a land no matter what else it happens to be. When no colorless target presents itself, the first mode points two damage at a blocker, so the card never rots in hand waiting for the right thing to break. That mutual coverage is the whole design: two modes that fill in for each other, on a 2/2 body that attacks without complaint before cashing itself in. The activation plus the sacrifice is the toll on all that flexibility; you spend a goblin rather than hold up an answer indefinitely. A burn spell and a narrow Naturalize variant stapled to a warm body, with no guesswork about which one you would rather have drawn.
