Nice! I've considered PPVP Adam, but never got around to trying it out. Also considering taking him to regionals, so high-five!
This feels like generic advice and as neat as your solutions are, are they really better than 2 Aarons?
Draw is nice for PPVP, and you mentioned trouble with tagstorm. Heck, if you got up to 3 Aarons, it's be easy to deal with MCA. And if you do end up going the Dean Lister route, know that he updates dynamically, so drawing a card mid-run would boost your breaker.
