Need Help in building a team


I just started playing like almost 2 months I can’t always log in and play but I try daily to get the special deals of summons.So all of the the characters that are good and are level 1 is because I recently just got it. Now what I have in my party is what I started with in my first day playing the game thats why goku,shallot,vegeta are maxed with tiers and level. I’ve been heading to pvp most of the times the 3 top characters work sometimes it doesn’t. I don’t spend money on the game I just work my ass off, so everything I have right now is not bought with real money and I am not planning on wasting any. So what I need help on is in making a new team thats more updated and better than what I have now. The Link that is shown is all the fighters I have
