Mobilise the Clan

Whenever one or more orcs you control attacks,
create a 2/2 red and green orc creature token
tapped and attacking. Then if you control five or
more attacking orcs create a 4/4 red and green
beast creature token with trample tapped and attacking.
"United behind its leader the clan marches across the steppe, growing with every mile it gains. Their true
number is impossible to estimate, not even counting the beasts." - Humboldt's wild volume
