The new PvP Duelist's set is something close to what you might mean. Amulets give 3 cards at the max so just pick wisely! I'd go for spells any school can boost their spells from. I think the accuracy needs to come down. I don't think any set should give more than eh... 15% Accuracy. But maybe some in game sets do give more. I can't remember. Good Idea though!
