Nez, Matrix Maestro

Whenever a non-token artifact you control is put
into a graveyard from the battlefield, create a 1/1
red Gremlin artifact creature token with
haste.
Whenever one or more gremlins you control deal
damage to a player, you may pay {1}{u}{r}. If you
do, create a copy of target creature that
player controls except it's an artifact in
addition to it's other types.
