I saw Twinflame and Prophetic Flamespeaker spoiled last night and it creates some great synergies with some existing cards. For example, Burning-Tree Emissary into Twinflame could open up lots of possibilities.
I truly like Prophetic Flamespeaker and I think he can fit in the Chandra's Phoenix spot. I'm used to playing mono red so if we're going to get rid of Chandra in the flyer spot, I need to splash white to get access to Chained to the Rocks. The sideboard is temporary, but I know they are good cards in the R/W standard now.
The point of this deck is aggro, Madcap Skills opens up lots of possibilities with Prophetic Flamespeaker, though I wish it had haste. Suggestions would be appreciated, since I'm new to Boros and I'm used to playing mono red. Thanks for checking out my brew. It may have a little too much hype behind it but I'll start play testing now to see what I like.

Strive - Twinflame costs 2R more to cast for each target beyond the first. Choose any number of target creatures you control. For each of them, put a token that's a copy of that creature onto the battlefield. These tokens have haste. Exile them at the beginning of the next end step.
