Copperworks Toy Shoppe

Copperworks Toy Shoppe enters the battlefield
tapped.
{t}: Add {u} or {r}.
{t}: If you control four or more artifacts with different names, each player creates a 0/1
colourless Toy artifact creature token.
The clockwork armies and war machines are a side
project at best. Even Copperface doesn't know why he
does it, but Belgazzio has more toy shops than
children.
