Tarjul, The Warmonger

Trample
Whenever a nontoken creature enters the
battlefield, you get an {e}.
Choose target nontoken creature: You may
pay an amount of {e} equal to that permanent's
converted mana cost. If you do, create a token
that is a copy of that permanent, except it is an
artifact in addition to its other types.
