Call the Spirit Dragons
A five-color enchantment that hands out an alternate win condition, with the whole trick living in the counter distribution. The upkeep clause is not "put five counters on your Dragons"; it is one counter per color, each on a Dragon of that color, which means the win only fires if you can spread counters across five distinct Dragons at once. That constraint is what pays for the payoff: a mono-white or two-color Dragon board never gets there no matter how wide it goes, so the card asks for a deliberately rainbow spread of Dragons rather than a big pile of them. Because the counters land during your upkeep, an opponent can get a window after the fifth Dragon resolves to disrupt the line before it triggers, and the win checks only if all five placements happen in the same upkeep. The indestructibility rider is the quieter half, and pointedly one-sided: it shields only the Dragons you control, keeping your assembled spread alive through removal and combat while doing nothing for anyone else. That asymmetry is what lets a slow, telegraphed wincon survive the turn it needs; a symmetric anthem would have handed opponents the same protection. Between the color-diversity demand and the upkeep timing, it is a payoff built to reward a Dragon deck that has already committed to five colors, not to bootstrap one.
