Cerlia, Foundry Queen

When Cerlia, Foundry Queen enters the
battlefield, create two 3/3 colorless Golem
artifact creature tokens.
Golem creatures you control have "When
this creature dies, its controller creates two 1/1
colorless Servo artifact creature tokens."
"I make them. When they serve their purpose, I melt
them down and make new ones. The cycle never
ends."
