Subjugating Plague

Create five 1/1 black locust creature tokens with
flying. Put X -1/-1 counters on each non-black creature where X is the number of locust
creatures on the battlefield.
If you control a creature named Abaddon, Lord
of Locusts, instead create ten 1/1 black locust creature tokens with flying.
The seal is broke, the maw of the pit, wide open.
-Abaddon, Lord of Locusts
