Golos, Tireless Pilgrim

Colorless in its casting cost but five-colored in its ambition, this is a creature that any deck can play and only one kind of deck can fully use. The enters-the-battlefield land tutor is the reason it slotted into everything for a while: it fixes, it ramps, it thins, and it does so for a body that blocks credibly, all without asking a thing about your mana to trigger. That first half is the utility infielder. The second half is the payoff for going all in: a Domain-style activation that demands one mana of every color and cashes it out into three free cards off the top, played the same turn. The five-color pip requirement is what pays for an effect that would otherwise be broken at any speed; you cannot fire it without having already committed your manabase to the rainbow, which is precisely the manabase the tutor exists to assemble. That symmetry is the whole design: a self-fixing engine whose ceiling scales with how many colors you can support and whose floor is still a fine value creature in a two-color pile. Wizards has printed plenty of "goodstuff" magnets over the years, but few package the ramp, the fixing, and the payoff into a single card that reads as generically as this one does while quietly rewarding the greediest possible build.
