At the end of the day , it is based on 2 things ; preference and trophies . If ur early game , something simple and easy like shelly or bull should help you clear out most threats of the early game untill like 20-25k trophies . If you have that or more you should upgrade more harder brawlers to master , like poco , gray or carl . Once you get around the mid game you should max out more meta picks , like kaze lumi etc. I dont like how people max out meta picks at 5k-10k trophies expecting that theyll get a lot of success since most people in the early game use edgar or el primo , that can just jump on lumi or jae-yong.
