Newcomer looking for help on team building

(Repost - Weird Google link didn’t work last time)

Same issues, confused by game no idea what to build. Did some research going with

SP - SSJ Kid Goku Green
SP - SSJ Bardock Blue
SP - Legendary SS Broly Green
SP - SSJ3 Goku Purple
EX - Goku Blue
EX - Kid Gohan Red

I know Kid Gohan is just a place holder I read that EX Raditz Blue is the way to go but not sure if this is the way to go just looking for some tips in general. Thanks in advance!!
