Darksword Shogun

Firststrike, menace
Whenever Darksword Shogun becomes untapped, other Samurai you control get +1/+0 and gain firststrike and menace until end of turn.
The Darksword samurai, under the command of their shogun, launched a campaign of terror on the neighboring shogun's villages. This uncalled for provocation is sure to subject the land to war for decades to come.
