The two-line design here is doing more than the tribal anthem suggests. The +1/+1 for Mounts and Vehicles is the obvious payoff, but the second line is the interesting engineering: by treating this Human's power as two greater for the purposes of saddling and crewing, it lets a modest 2/3 body single-handedly turn on Vehicles and Mounts that would normally demand a much heavier commitment. That solves the recurring friction of the whole mechanic, which is that a Vehicle costed for a big crew number sits inert until you have enough board presence to animate it, and a Mount asks you to expend a creature's combat step saddling it. This card lets one small body meet those requirements alone, and because the anthem stacks with the vehicle it just crewed, the thing it turns on also gets bigger. It is a lord and a crew engine folded into the same three-drop, which is the kind of dual-purpose framing that keeps an artifact-and-Mount deck from stalling out when it draws the payoffs but not the enablers. The restraint is in the body: a 2/3 that gives everything else the buff but keeps almost none of it, so the card wants a battlefield to point its abilities at rather than a fight of its own.
