Twelve, Soulless Shifter

Kicker {4}
When this creature enters the battlefield, if it
was kicked, create a token that's a copy of it,
except it's not legendary and is named Thirteen.
Whenever a legendary creature enters the battle-
field, you may have this creature become a copy
of it except its name is this creature's name, it's
an artifact in addition to its other types and it
has this ability.
