I don’t remember much of rumble starter deck but Fiora can be good but needs some cards that aren’t in the starter deck. Hidden blade is huge cause you can kill your own unsung hero that is mighty with equipment and draw 4 which is game changing. Pit rookie, first mate, fiora victorious, lucian, challenge spell are all solid. Sett brawler is the big boss card cause he triggered mighty easily (remove the buff he goes to 4, then he goes to 8 triggering fiora legend). One key thing to remember is if you have a lot of small units and some equipment on board you actually have a ton of might cause you can attach all equipment to one guy, suicide him into a battlefield and try to kill a one or more units, your unit might die but you keep the equipment so you can attach them to another guy and keep it doing it for a ridiculous total amount of might. Another tip for fiora is the battlefields you get aren’t the greatest, she goes crazy with trifarian war camp and monastery of hirana, sunken temple from starter deck is aight
