I felt like I should ask this, but should Raizel and Mash slowly gain the stats and certain skills of the servants they have over time? (For example, if Raizel carried Archer Emiya in his Inventory/briefcase for a week, he will slowly gain the reaction speed or marksmanship of Archer Emiya, course I'll leave out the truly OP skills.) I will try this idea out in the next chapter, and if given the okay I'll continue doing it.
Now mind you they won't become godlike in strength, endurance and agility, they will have a cap in their gains, that way they don't go too overpowered for the beyblade verse.
But what do you guys think?
