Sorcery
Choose target artifact creature you control. For each creature chosen this way, create a token that's a copy of it.
Overload
(You may cast this spell for its overload cost. If you do, change its text by replacing all instances of "target" with "each.")
Effects that cause you to pay more or less for a spell will cause you to pay that much more or less while casting it for its overload cost, too.
