also level up as much as you can to regenerate your cubes and accept all boss battles, you dont have to carry through with them but then if you get a couple you can pick the higher pointed ones if your limited with cubes.
additionally get to know what damage your deck can do on 1, 2 and 3 cubes, no point wasitng a cube using 2 if you can defeat a boss with 1.
my deck out of episodes is currently 8260 i have been rebuilding it, max upgrade your bot and alt modes first, trans-scan and then max upgrade again this gives the cards higher stats.
Also i found that upgrading during an event is easier as it seems you get double value for your cards, same goes for selling. so you can upgrade quicker
