your deck should be relevant to the stats you plan on focusing the most during the run (for example, Stamina since the next event is a Long) but also you can use the two sites above to look at which skills you get from each card and how much of a bonus you get
alternatively you can just be a based retard and just pick a random uma and then just use all your highest lvl cards and do whatever you want. will probably work too
