The point is not to have a Pulvy or not.
The point is to have a good pool of PC. Against Firestall, mono-aether etc, you will need 2/3 PC. In this JMZ, you have Pulv, Steal, Crusader-Pulv.
You also need to respect the balance of quanta usage. If you don't play Pulveriser and add a Vampire dagger, you have to wonder if you won't have too much Earth and not enough Darkness.
I play a Vampire dagger with Crusader in my rainbow, it's strong. But I have enough PC aside of it.
