I want to build a Gideon of the Trials + all of the bad red timewalks deck. Other than those cards, what shell should I use? I was thinking some sort of Jeskai mentor type list that gives up longevity for way more burst since mentor synergizes so well with time walk and pact of negation + force is a lot of countermagic to land gideon and friends.
I know the deck will be shit but what any recommendations?
