Okay, so you're in your room, or wherever you are, you play some blockland. You have this blockland skyscraper you are planning to build and you type your duplicator out, and the computer screen just shoots a duplicator at your face, you wake up in a sweat, and you have a duplicator in your hand. Sweet. what would you duplicate?
OFF-OFFTOPIC:

I got this idea from my friend named Buddy! and I kept on getting squilite errors, and I told him humanity would make a time machine and go through 892470924 light years and there would be no such thing as lag. then I thought up if the year 892470924 had a duplicator because it's so high tech.
Good luck thinking!
