Tepali, the Packleader

Creature tokens each get +1/+1 for each token
their controller controls with a different name.
Whenever an opponent creates one or more
creature tokens, create a copy of target creature
you control unless that player sacrifices a
nontoken creature.
{3}{g}{u}{r}, {t}: Each player creates a 2/2 red
dinosaur creature token. Then, each player
populates.
