Inquisitive Captain

Vigilance

Whenever you surveil, Samurais and Warriors you
control get bushido 1. (Whenever a creature with
bushido blocks or becomes blocked, it gets +1/+1 until
end of turn. If a creature has multiple instances of
bushido, each triggers separately.)

{t}: Surveil 1 (Look at the top card of your library.
You may put it into your graveyard.)
