Yaag Rosch, For the People

When Yaag Rosch, For the People enters the battlefield, create a white 2/1 PSICOM Soldier
creature token.
PSICOM Soldiers you control have first strike
and banding. (Creatures with banding may attack
or block together in a band. When a banded creature
is fought, the band is fought instead. When a band is fought, you distribute the opponent's creatures' combat
damage, not its controller.)
Sacrifice Yaag Rosch: Destroy all black or green creatures fighting Yaag Rosch.
