UnCommander Rulings
Note that UnCommander generally follows regular Commander rules, so rule 13 in the Commander Rules prohibits effects from bringing objects from outside the game into the game by default. If you want to allow these effects to fetch certain objects, it needs to be negotiated in your playgroup.
