Vaalmonica doesn't have to do elaborate pendulum combos. It just specials level 4s when it gets its scales up. Vaalmonica is weird. Look up a few combos to learn it. The combos aren't hard or long, but the cards are weird so it's hard to figure out how you're supposed to use them just from reading them.
It's best with Fiendsmith since it has an archetypal light fiend so can extend into it easily, and can use Tract to search Dimonno.
