Background
I have a Paladin that reveres Mystra, and would like to be take as much advantage of spells as possible. The DM has allowed the Serenity feat - which is excellent for reducing MAD. Of course, you can't really take Paladin spells seriously without taking the Battle Blessing feat.
Dilemma
If I was rather unsatisfied with the Paladin spell list, and decided on taking the Sword of the Arcane Order feat, would the wizard spells that I gain in my Paladin spell slots still be considered Paladin spells? What effect would taking the Winter's Champion feat have if I selected Sword of the Arcane Order?
Revision Due to Comments
If I took the Magical Training feat, I would gain a spellbook, and three 0-level spells. With Sword of the Arcane Order, I would not be restricted from "borrowing from someone else's spellbook," correct?
