@DeltaBladeX I decided I wouldn't use the same version of Artoria twice as Grand. It's kind of complicated, I'll try to explain it. Think about the New Year all-Artoria music performance: in that instance you can see that the base versions and the Alter versions coexist as different entities, while summer/christmas/idol versions are considered reskins. So, I took that as model and since Lion King is already my Grand Lancer, Ruler Lion King can't get that title. This makes sense, and also allows me to give a couple of spots to my other favorites (Alice, my n.2 in all TM, will take the caster slot. while Ciel is my n. 3 and got the extra 1 slot).
There will be only one exception to this rule, that being the archer version, for two reasons: 1) I can't say no to OG Artoria; 2) I don't have Jeanne Archer, the only one that I might have considered as a worthy substitute.
Hope this explains it.
