UnCommander Rulings
UnCommander rules do not normally allow events in one game to have an effect on another game, even if the games are both part of the same match. See The Game, Separate Games and External People.
UnCommander follows the regular Commander rules. As such, rule 11 in the Commander Rules prevents effects from bringing objects from outside the game into the game by default. This includes cards from a sideboard. If you want to allow these effects to fetch certain objects, it needs to be negotiated in your playgroup.
