Bog Initiate

Filtering one generic mana into black, this is mana plumbing in its purest form: a 1/1 Wizard whose only job is to convert colorless or off-color mana into the black you actually want to spend. The trade is its own activation cost, so it never accelerates you the way Llanowar Elves does; it launders mana rather than ramping it, turning an artifact source or an off-color rock into something a double-black spell can use. In a high-fixing-demand era of punishing color requirements, that translation work justifies the slot even when the rate looks unremarkable next to dorks that produce a net mana. The body is incidental, a place to hang the ability rather than a creature anyone deploys for combat, and its Wizard typing is the only thread that ever connected it to anything beyond pure infrastructure. Built to smooth a color-screw problem at humble rarity, it earns its keep precisely when your mana base is unreliable and goes forgotten the moment it is not.
