Boros Guildmage

A casting cost that bends to either red or white mana lets this body land off whatever the board is producing, but the abilities draw a harder line: haste is bought with red (), first strike with white (), and the creature can only fire what its lands support. That asymmetry quietly taxes a one-color build, since committing fully to either side strands half the text, so the frame wants a deck genuinely producing both colors. What the investment buys is combat shaping rather than raw power. Granting haste turns a fresh threat into an immediate attacker, erasing the summoning-sickness window that usually hands an opponent a free turn. First strike retools a combat step so your blocker eats the attacker before it can swing back, or your attacker pushes through clean. Neither ability taps the guildmage, so two open mana fires one off every turn it survives, and a deck willing to spend four can stack both onto a single creature in the same combat. The 2/2 body dies to nearly everything, which forces the value to be banked early and often. This is a creature built for boards that want to convert a stalled attack into lethal by deciding who arrives early and who strikes first, and like every guildmage of its line, its whole job is to turn surplus mana into small, repeatable combat edges rather than to win a fight on stats alone.
