Why? It seems to me that it would work just fine, just like Hp do. I don't see why having a six-attribute system interferes with mana-pool ideas.
@Wombat Vancian magic is technically a magic system where spells erase themselves from the mage's mind after use, but it is generally used for any system where you have to pick exactly which spells you are going to be able to cast and you can't cast a spell twice unless you "researched" it twice.
