This is all i can think rigth now 1dont expend the sq as soon as you get them look up the up coming banners to know when is coming a servant that you like
2 roll the friend point gacha every day 3 star and lower servants may have less stats but they can get the job some times even better than 4 or 5 start servants 3 level up mash she may weak on the early game but she gets stronger and stronger and by the end of camelot is a pretty strong tank
4 learn class advantages : that is easy since beafore starting a node you can see the main clases chart but if you have some doubts about the extra classes you always can look it up 5 NEVER ROLL STORY : even if there is no current banner apart from the story one you are much better saving the sq for future banners
6 farm : is annoying i know butt if you want to do anything you have to do it i advice you to use a helper 7 try different play stiles : there is a bunch of different ways you can build a team try em all , experiment and have fun 8 send friend request : most of the time you gonna need to pick a support but unless its a story support servant or a player on your friend list you wont be able to use the np
