I am familiar and have marked most of the expansions as familiar to me. However, when I use the match feature to find a person to play against, I get these tables with all the cards I am not familiar with.
Is there any way to tune the match to match only against those tables that have the cards I am familiar with and not the rest?
I assume you join a *rated* game, by clicking on the "Two player" button. Those rated games don't respect familiar cards. If you want a game that respect your (and opponent's) familiar card settings, click on "practice game".
