Clay Wizard

Wizards without echo have echo {4}.

At the beginning of your pre-combat main phase,
for each wizard, if you paid that wizard's echo cost
this turn, create a token that's a copy of that wizard,
only it's an artifact and Golem in addition to it's
other types.

When a Wizard you control dies during your
upkeep, create a 3/3 Golem Wizard artifact creature
token.
