I started about a month ago, and I want to try out 4-5-1 V. How should I setup team orders and what players should have arrows? Should I switch this around depending on the setup I meet?.

I'm also not sure whether I should buy players with special abilitys and what abilitys they should have. Example, is it better to buy a player with 5 stars with no ability, or a player with 4 stars and an ability?
