Not to be a downer, but your deck doesn't function. Merchant's scroll only gets blue instants, which in your deck is
peek and merchant's scroll; you're missing
gifts ungiven.
Infernal tutor is also not great, it's great as the last spell in your hand or when setting up, but has so many problems, like having two in hand, excess of lands, an excess Baral, and there's many more I can think of. This is a good attempt but you need more refining.
