An Illusion of one or more creatures forms over the Thrown card and remains until dispelled. An illusory creature appears real of the appropriate size and behaves as if it were a real creature except that it can do no harm.
While you are within 120 feet of the illusory creature and can see it you can use an action to move it magically anywhere within 30 feet of its card. Any physical interaction with the illusory creature reveals it to be an Illusion, because Objects pass through it.
Someone who uses an action to visually inspect the creature identifies it as illusory with a successful DC 15 Intelligence (Investigation) check. The creature then appears translucent.
