Lux Artillery

The number that makes this work is thirty, and reaching it is a deckbuilding exercise dressed up as a payoff. Sunburst has always been the counter mechanic that rewards a greedy manabase: pour four or five colors into an artifact creature and it walks in fat with a counter for each, while paying with a single color yields just one and paying with only colorless mana yields none at all. This card turns that per-creature reward into an accumulator, granting sunburst to every artifact creature spell you cast so the counters spread across your whole board rather than resting on one threat. The end-step check is the honest part of the design: it counts every counter on artifacts and creatures you control, not just the ones this granted, so charge counters, oil counters, and any other +1/+1 source all feed the same threshold. Cross thirty and each opponent takes ten, a burst large enough to end a table in a single trigger and to close a duel in short order. The friction is that thirty is a real fence. You are asked to run four or five colors of fixing so the sunburst grant pays out fully, to flood the board with counter-bearing artifacts, and to survive to your own end step with the count intact. It is a build-around that names its own archetype: WUBRG artifacts, wide and counter-dense, paying the generic cost in as many colors as the mana can stretch to.
