Endless Atlas

Three or more lands with the same name: that single activation gate does all the sorting. A two-color pile spread across duals and one basic of each type stares at this rock doing nothing, while a deck flooded with a single basic switches it on the moment it resolves. The inversion is deliberate. Colorless card advantage usually flows to whoever splashes for it, but this rewards the opposite behavior, aiming itself at the mono-color decks that most struggle to keep gas in hand. Mono-white and mono-red have long leaned on artifacts and enchantments for refills because their colors offer little raw draw; a repeatable colorless draw source that only functions on a uniform manabase is a subsidy built for exactly those archetypes. The engine underneath is clean work: card advantage on no clock, so you can leave mana up and draw whenever you like, on a permanent that ducks the creature-based sweepers by not being a creature. What defines it also disqualifies it from the generic-goodstuff pile: it refuses to pay out for greedy five-color fixing and instead compensates color discipline. The result reads as filler and plays as a reward for committing to one color.
