How it works
Activate Lithatog by sacrificing Tom, Bert, and William.
When Tom, Bert, and William die, they trigger, returning them from your graveyard to the battlefield as a noncreature artifact.
Because Tom, Bert, and William enter as a noncreature artifact, March of the Machines will then cause Tom, Bert, and William to be a 5/5 artifact creature.
