Shino, Sentient Hive

When Shino enters the battlefield, create a
number of green and black 0/1 Insect creature
tokens with "Whenever this creature blocks or
becomes blocked, put a -1/-1 counter on that
creature" equal to the highest toughness among
creatures on the battlefield.
{1}{b/g}: Insect creatures you control get +1/+0
until end of turn.
"Never underestimate your opponent, no matter how
small they may seem."
