GN-MTRX

At the beginning of your combat, put a +1/+1 counter on each creature you control with at least
one ability counter on it.
Whenever a creature with a +1/+1 counter on it deals combat damage to a player, create a 1/1 black
and green Cy-Bug token with “This creature enters with one of that creature’s ability counter on
it.”

“Each improved bug becomes the root of a new swarm branch.”
