When I run B/X DnD, I will probably use Labyrinth Lord because of it's organization. I wanted to present all of the relative information about each class for my players in one block.
Additionally, I'm tweaking each class with some house rules that reach out to other editions of DnD.
Changes to the class are in yellow.
Magic-User

Prime Requisite: INT

• Cast magic-user spells

(when a virge targets a creature it must make a
save vs wands or suffer 1d6 damage. However,
it can only be used if the magic-user has at least one
unused spell slot left)
