Tin Street Hooligan

The conditional artifact destruction is the whole design conceit: this is a mono-red goblin whose relevant text only fires if green helped pay for it. The body costs , but the destroy effect is gated behind reaching into green, which means the card is really written for a Gruul shell rather than a pure red deck. Cast on red alone it is just a 2/1, a fine enough early body that does nothing about the artifacts it was named to break. Add the green and the same two-drop becomes a Shatter stapled to a creature, answering a mana rock, a piece of equipment, or any artifact the turn it lands. The lineage here is the long red-green tradition of artifact hate riding on a body: the colors that historically resented mana-fixing and noncreature engines got tools that demanded board commitment to use. What makes this one a clean piece of design is that the conditional is a deckbuilding tax, not a discount: you do not get the destroy effect cheaper for splashing green, you get a worse card if you cannot reach it. It rewards a mana base built to support both colors and quietly punishes the player who jammed it into the wrong deck.
