When Mirror Golem comes into play may I target multiple cards to imprint to him?
{Mirror Golem}. Remember to use curly brackets to link cards, so everyone knows what you're talking about!
Imprint only allows you to exile one card for its ability, I'm afraid. If you look carefully, you can see it in the text itself. For imprint, you may exile target "card" and it has protection from the imprinted "card's" types.

Thank you! Nice tip on the brackets, too.
