Sensei Golden-Tail

Bushido is one of the few keywords that lives entirely inside combat, scaling a creature's body the moment it blocks or becomes blocked, on offense or defense alike. The interesting move here is not embodying that keyword but distributing it. The training-counter ability is an engine that propagates a mechanic instead of spending one, slowly converting a wide army into Samurai one creature per turn. The sorcery-speed restriction keeps the gift from doubling as a combat trick: you cannot flash bushido onto a blocker mid-fight to steal a trade, so the upgrade is a project played across turns rather than an ambush. The counters are permanent, and they stack: a creature trained twice carries two separate instances of bushido 1, each triggering on its own when that creature blocks or becomes blocked, so the boost compounds the longer the engine runs. The tap cost is what rations the spread. The tribal rider matters as much as the combat math, since the trained creature literally becomes a Samurai in addition to its types, feeding anything that cares about the type. The deckbuilding logic is inverted here: a 2/1 that adds almost nothing on its own swing devotes its whole purpose to a patient, growing board, asking every creature to fight a little better over time. Most bushido creatures wear the keyword. This fox manufactures it, a quiet inversion of how the mechanic was meant to read.
