Sure no problems at all with the base, expansions and Dragon booster. They were all made to go together and work really well.

Get's Promoted booster may have some issues. It's a mix of cards from different sets so not all of the backs are the same. Most are the original back, but I can't remember the exact breakdown there are at least 4 of them. So if you care about matching backs that is an issue. Also the ones with different backs may not apply to the game. I know "Whim of the Elder Gods" card is included and that has a Cthulhu back and requires at least one Cthulhu die to be useful. I can't remember if the other cards have anything that is specific to their sets.
