Grishnákh, Brash Instigato

When Grishnákh, Brash Instigator
enters the battlefield, amass Orcs 2.
When you do, until end of turn, gain
control of target nonlegendary creature
an opponent controls with power less
than or equal to the amassed Army’s
power. Untap that creature. It gains
haste until end of turn.
