Crossroads Consecrator

Tribal anthem effects usually arrive as static buffs that hit every member of a type at once; this one charges per use. The mana-and-tap activation pumps exactly one attacking Human, which makes it less a lord and more a repeatable combat assist that scales with how many turns you have a green source open. The restriction to attacking creatures is the line that keeps it grounded: it does nothing on defense, can only push damage through, and rewards a board that is already going wide and forward. That narrows the card to dedicated Human aggro, where a one-drop body doubles as an engine that turns a stalled attacker into a chunk of extra reach. It belongs to a tradition of cheap creatures that sell their own modest stats to buy a recurring tribal effect, and like most of them it asks the deck around it to do the heavy lifting before the ability matters at all.
