Mono-Red was the aggro deck that defined Standard before Dominaria hit. In the wake of Dominaria, things are very different. There are all manner of new and exciting things to try, and one of them is this whacky Mono-Blue deck from NebraskaBrandon which may well be a new aggressive baseline for the format:

What's really exciting is that there are multiple ways to build this deck. You can go even lower to the ground with more one-drops and play Throne of the God-Pharaoh in place of or in addition to Favorable Winds. It's refreshing to see a new aggressive deck that looks like it has the tools to compete in this format, especially one that attacks in such a different way from the Red decks that we're used to.
