Enter the Infinite seems like the most broken thing to do, since it draws us our entire deck, and in theory, if we draw our entire deck, we should be able to have some combo that wins us the game (a bunch of Simian Spirit Guides and Lightning Storm is an easy example, or perhaps something involving Laboratory Maniac), but we could also try to use Wildfire Eternal with extra-turn spells like Time Stretch, which give us additional attacks to keep triggering Wildfire Eternal and casting more free spells
