At the beginning of combat on your turn, draw a card. Then you may exile an artifact or creature card from your hand. If you do, create a token that's a copy of the exiled card, except it's a 3/3 Golem artifact creature in addition to its other types.
Any enters-the-battlefield abilities of the copied card will trigger when the token enters the battlefield. Any “as [this permanent] enters the battlefield” or “[this permanent] enters the battlefield with” abilities of the copied card will also work.
Except for the listed exceptions, the token copies exactly what’s printed on the exiled card and nothing else.
If the exiled card has {X} in its mana cost, X is 0.
