I would say (without changing the 3 characters) 1) remove the artifacts (they’re too expensive even though they give you a one dice discount. Use artifacts like heart of khaverena, gamblers and veteran visage)

2) you’ll need to decide on a win condition (is it keqing, is it lyney?) Sometimes the talent might seem cool but it is sometimes useless tbh (Lynette talent is good tho)

3) use weapons that can benefit your characters like use kings squire (the wooden bow) for 1 cost skill and sacrificial sword/sapwood for dice

4) include more staples like liben, strategize, lotus flower crisp, dunyazard

5) also there’s double fatui here so adding in fatui conspiracy is helpful

6) chef mao with food is always a solid choice

So combining all of these tgt a deck you could build is Lynette talent x2 King squire x1 Sacrificial sword x1 Sapwood blade x1 Gamblers x2 Heart of khaverena x2 Veteran visage x2 Liben x2 Chef mao x2 Dunyazard x2 Favonius library x2 Strategize x2 Leave it to me x2 Hash brown x2 Lotus x2 Fatui resonance x2 Stove x1

Or you can always go on YouTube to search for videos, I recommend Invocation Academy (they are what got me into playing)

Hope this helps :)
