Marshal of Zhalfir

A Knight lord in white-blue is already an odd pairing: the tribe historically lived in mono-white and Boros aggression, where a static anthem was the whole payoff. The activated ability is what pulls this into the blue half of its identity. Paying WU and tapping it down turns a two-drop lord into a repeatable soft-removal engine: knock a blocker out of the way before your Knights swing, or tap a potential attacker before your opponent declares attackers so it can never swing at all. The wording matters. The tap symbol in the cost means the Marshal has to tap itself to activate, so it cannot fuel the ability while also swinging, and the "another" clause simply stops it from targeting itself with the effect. Otherwise the targeting is open: an opposing threat, or one of your own creatures if you have a reason to. The tension the design resolves is that a 2/2 anthem on an empty board accomplishes nothing; the tap ability gives the card a job before you have assembled a Knight shell, so it keeps earning its slot while the tribe comes online. The first line reads like tribal-support filler, but the second line is doing the work of a control piece, which is why the card lives in exactly one color pair rather than the tribe's traditional home.
