Suntouched Myr

The naked demonstration of Sunburst, stripped of any other text to distract from it. The 0/0 body is the whole point: cast it with only colorless mana and it never makes it past resolution, since it enters with no counters to prop up its toughness. Spend a single colored source and it survives as a 1/1; the most diverse line, three colors across its three generic pips, hands you a 3/3. Every point of stats is purchased with color spread, which makes this a creature whose existence is gated entirely by your manabase. It is Sunburst as a teaching card, the cleanest expression of the mechanic's central bargain: power scales with how many colors you can produce, and the keyword quietly taxes the focused deck while paying out the greedy one. The artifact creatures that wore Sunburst in this era mostly bolted the keyword onto a body or effect that did something on the floor. This one offers nothing else. It is the mechanic with the training wheels removed, a colorless Myr built to prove that an artifact shell can still demand a spread of colored sources just to function. The design tension it resolves is whether Sunburst could carry a creature entirely on its own back, and the answer, written into a 0/0, is barely: without at least one color in the cost, you have spent three mana to put nothing on the battlefield.
