The servants I plan to roll for the coming year are Cu Chulainn (Alter) (I think the next time he shows up maybe my last chance), Meltryllis (so I have a Quick boss kill if needed), a single target and damage to all enemies berserker Arts dealer, and save for the next Meta support servant. If they follow JP which they should then in 2022, if he doesn't spook me before, Waver is a guaranteed.
