Koichi Hirose & Echoes

When Koichi enters the battlefield, create a 1/1 blue Stand creature token with flying named
"ACT 1", a 2/2 green Stand creature token
named "ACT 2", and a 3/2 blue Stand creature token named "ACT 3" with "Whenever this creature deals damage to another creature,
tap that creature. It doesn't untap during its controller's next untap step."
