Lola Hayes doesn't care which role she is

Someone asked me to publish my Lola decklist this is it.

The basic idea here, is that you want to accumulate and rely on strong passive effects from various classes because these effects work regardless of what role you are using. If things work out well for you, you can get pretty high base stats and make up the difference for trickier tests primarily with skills and extra actions. You'll never be particularly good at any one thing but at any point where you can accumulate two bonuses to anything, you can do decently enough to reliably handle easy checks. Ideally, other more specialized members of your party will handle the other things. We do not want assets whose main purposes are their triggered abilities as that will inevitably lead to us tripping over ourselves wanting to use cards from multiple roles at once. --The exception to the rule that you're looking for assets purely for their passive abilities are attack actions and cards that let you 'spend resources for skill' cards. Although it is limiting only being able to fight in whichever suit you've drawn your attack assets in, it's still mostly manageable, it just limits our selection of events and skills very slightly. Hard Knocks is mostly a placeholder that might help you get value from Dark Horse and you'll be wanting to replace it with a permanent later.

Early in the campaign, the key cards are Dark Horse and Leo. Ideally you'll want both but at minimum getting one or the other should be a high priority. You'll notice that (with the exception of leo) the overall cost curve of the deck is very low and that it uses a much higher than normal number of skills. This is largely to support use of dark horse but it also serves to help your efficiency as skills do their thing without costing actions or resources and many of them replace themselves. You can still get bursts of resources from emergency caches and improvisation to play new assets when you get them but in general you're hoping to get dark horse and then either spend resources as you get them or simply decline to pick them up.

As you advance your character, dark horse and skills will become less essential as you replace cards with more allies and assets that passively grant stats. You should get Charisma to allow you to hold more allies and grab the permanent versions of the 'spend resource for skill' cards (one for each class) to help make it easier to get value from dark horse. You should also consider branching out to get strong passives from the guardian and seeker class. So long as you aren't expecting to play more than one card a turn normally and don't need to either commit a class specific skill, it really doesn't matter how many classes you have in your deck.
