This list is an improvement from my previous Alternate Boros, but it was not created by me. It was created by Kedi and I lifted the list 100% verbatim and posted it here, but I'm pretty sure he would be okay with that.

I tested it out a few games and it plays faster and better than my previous Boros, but it does have just a tiny bit less late-game staying power. However, the old list didn't have a large late-game anyway, so this list is better than the previous one.

Since it's not my list, I'm not exactly sure how you board, but I imagine Harm's Way for red damage spells and Purge for black things works well. Baneslayer for the mirror and Eldrazi, and more Rangers and Barbs for big control decks.

Try it out.
