Kozilek's Channeler

A 4/4 that taps for two colorless is an odd creature to build around: the body is large enough to block and trade, but its real job is bridging a midgame mana gap toward the cast cost of something enormous. This is the ramp-rock problem recast as a creature rather than an artifact. Where the classic mana rocks turned two or three mana into colorless acceleration early, this one lands the same output on a body that contributes to the board while it waits, and the colorless specificity is the point: it is acceleration built to feed cast triggers and devoid-flavored payoffs, not generic fixing. Because the acceleration arrives late and is summoning-sick the turn it lands, it never threatens the explosive early starts that made fast artifact mana a perennial ban target. What you get instead is a self-protecting ramp piece: harder to hit with artifact removal, capable of pressuring or absorbing damage, and worth its line even when the giant payoff is stuck in the bottom half of the library. It is a deliberately humble link in a chain whose end is something with eight or more in the corner, designed for the player whose plan is to out-mana the table rather than out-tempo it.
