Ready to battle again, after a lot of time away from Mtg..... I'm preparing the SB after the top's ban of course. It's based on the old Brandon/Rodrigo's guide, this is my idea on how to update it. Some consideration:
*I keep green: decay is the best universal answer, and xantid can win alone some games.
*Dark petition is not here against oppo's surgical, it's more like a replacemente for nauseam when I have to side it out. Any opponent can play surgical in theory, I don't wanna waste 1 side-in slot every time. DP can also be a burning wish, or pyroclasm maybe, I'm not 100% sure.
*against wasteland deck, rain of filth is bad.
*against discard, mox is generally out
*I think all the cards in SB are used against different matchups, it's quite optimized. The only thing is dread of night, but it's soooo good against D&T. And with the fucking mum, decay/bounce are quite useless, I don't find any other good options

Hope to test it soon!!!
