Well IMO you want to grab every tutor imaginable: Demonic Tutor , Diabolic Tutor , Diabolic Revelation , Beseech the Queen , Liliana Vess , (if your budget is godly) Vampiric Tutor , and Imperial Seal .
Thats all form me. relentless rats decks always look like CRAZY fun.
Lol, I think you should just stick with your gameplan (get rats on the field and swing). You don't need protection for your general, you don't need tutor spells. All you need is the rats. The extra cards (if you hit them) are just an added bonus. They are not vital to the game plan.
