Limac, Explorer's Bane

When Limac, Explorer's Bane enters the battlefield, exile all creatures that attacked last
turn. For each creature exiled this way, insects
you control get +1/+1 until end of turn.
There came an explorer. He thought he was safe,
because he had guns, scent-masking spray and other
junk like that. Limac and his children ate well that
day.
