Manakin

A mana rock that has to be summoned, which inverts the usual tradeoff for colorless acceleration. Where Mind Stone or Star Compass produces mana the turn it lands, a creature-bodied accelerant pays summoning sickness on entry: the mana it makes is delayed a turn, and the body it carries can be killed before it ever taps. On the ramp axis that delay is a real cost. But the Construct frame buys something back. As a 1/1 artifact creature it answers to creature spells, blocks in a pinch, and feeds anything that counts bodies: sacrifice fodder, Construct payoffs, an anthem or counter that wants a creature already on the board. The fixed cost paired with a colorless output makes it the most generic possible version of this idea, the reason it found work in the years when colorless ramp on a stick was scarce. It sits early in a long line of mana-creature-meets-mana-rock hybrids, the slot Wizards has returned to whenever a deck wanted acceleration that doubled as a target for creature synergies rather than artifact ones. Plain and deliberate, built around a single bargain: a turn of speed surrendered for a body that an aristocrats or tribal shell can actually use.
