Coiled Tinviper

A colorless first striker that exists so any deck, regardless of color commitment, can field a body that wins the combat math against a 2/2. The design logic is purely about access: first strike is normally a white or red keyword, paid for in those colors at a discount (white or red would charge roughly two mana for a small first striker), but an artifact creature launders the ability into any shell willing to pay the colorless tax for it. That tax is the whole transaction. Stapling first strike onto an artifact costs more total mana than the same line in colored mana would, and the markup is exactly what buys the color independence. The 2/1 frame is the tell: first strike lets it eat most early ground creatures clean (its damage lands first, killing the blocker before it can swing back), but the single toughness keeps it honest against any incidental damage and prices it as a body that blocks well and attacks adequately rather than one that dominates. Vanilla-plus artifact creatures like this filled out the colorless-creature slot in older sets before that role was handed to flashier designs: no synergy hook, no second ability, just a keyword on a small body, sold at the artifact premium to whatever deck wanted combat math it could not otherwise afford in its own colors.
