Golden Egg

The design trick here is fusing a mana rock and a cantrip into one two-mana slot. It enters, draws a card, then sits as a permanent that either fixes any color once or converts into three life. That opening draw is what elevates it above the usual fixing artifact: it replaces itself the moment it resolves, so the fixing and the lifegain come functionally free, paid for by the card you drew back. The result is a fixing source that never costs you a card in hand, which is why it slots quietly into decks that want smooth mana without diluting their average card quality. It also happens to be a Food, so the same body that filters your mana can feed sacrifice payoffs and lifegain-matters engines: an artifact for the affinity-adjacent lines, a Food for the aristocrats-adjacent ones, a cantrip for everyone. The two sacrifice modes are deliberately asymmetric in cost, color-fixing at one mana and life at two, so the card leans toward smoothing your draws first and gaining life only when nothing better presents itself. None of the three effects is powerful in isolation; the whole point is stacking small, always-relevant utilities onto a chassis that refunds its own card slot.
