Arch-Commander Leopolda

If you control at least 3 creatures with "Iron
Order" in their name, Arch-Commander
Leopolda has Indestructible.
Creatures you control with "When this creature attacks" effect all creatures you control.
If Arch-Commander Leopolda is your commander, you may have up to four duplicates of creatures with
"Iron Order" in their name, unless the card says otherwise.
