One per day just like you suspect, grind at the Berserker Node (which was available Day 1) until 400, then grind 10/20 AP to get the 200 of each for the other two. Grind at Rider until bored of getting scripts, then progressively grind as each of the missions unlock, higher difficulty = better drop rates (I'd ignore Archer though, that ones got too much diversity).

Best nodes

Scripts-ALL (last day node)

Mona Lisa- Saber

Vitruvian-Lancer

Self Portrait-Assassin (but if you have 4-5 relevant CE from the gatcha, 20AP is better)
