two pattern major pattern :

1. You like the servant so why not?

2. The servant is good but you want some stat to make it better.

the first is clear so I won't touch it, the latter are much more important if you wanted to pursue efficiency for satisfaction purpose...

now there's 3 taboo for picking a servant to grail.

1. Do not Max Grail SSR with certain exception, that is Jeanne Alter and Cu Alter. Reason? because there's only 15+ Grail out so far, for SSR each Grail will only netted you 200 stat while for lower rarity you could gain at least 500 stat per grail up to level 90.

2. DO NOT GRAIL SUPPORT, I REPEAT NO GRAIL SUPPORT. it's obvious that support won't benefit from any stat addition because 1k hp are insignificant while 1k atk are useless for them. IF you must Grail Hans however it's fine, his stat are skewed towards HP so at level 90 he'll sit at 14k hp removing his only weakness that is his frailness

3. Do not Grail over 90.. reason same as number 1. this one is optional tho.. typically only JAlter shine brightly at level 100.. especially if you gold Fou her she'll sit at 18k atk.. that's 5k above average SSR atk... other than her any level 100 I saw is a waste logically speaking.

Note that this is just general pointer, you can ignore it if you want, it's just the logical approach but not necessarily the best one, it's a game so the point is your enjoyment.. for example personally I like to put servant on same set at same level.. for example All Alter should sit at level 90, all Tamamo at level 90, Gorgon SIster at level 80, etc.

anyway for servant to pick, point is they need to be good,, someone who already good by themselves but need more stat should be prioritized, the most obvious example is welfare servant. Welfare servant have lower stat total (20k) compared to other SR with total average stat of 22k, therefore with Grailing them you'll put them as bonafide SR, a lot of welfare are better than most servant so I highly reccomend this (personally I've grailed Kintoki, Santa Alter, JAilter, and Chloe)

other than that obvious one like Heracles or Lancelot.. in short the most effective method is picking servant SR or below and raise it to 90.
