Skittering Imps

Skittering Imps can't block
Nightfall: Skittering Imps gain Menace
until the end of turn. (Nightfall, triggers
the first time a Swamp or mono-Black creature enters
the battlefield under your control.)
"If there is a route around you they'll find it. Even
if it seems to small for aught but air. A good sword
borther at your back is needed to keep the the
creepers of Terra Innanis at bay." - Imperia
