This is a R/B Vampire Tribal deck I whipped up for play in Modern. Think it has the potential to be very competitive, but I still need to aquire many of the cards to build it. I would love some feedback on it and to know if anything should be added/removed, plus help on what to do with sideboard. For reference my FNM meta is a few R/W/U controls, some tron, A couple Bant, one Jund, and one Merfolk. (these are the regulars at least, sometimes see affinity, SS, others)

So Advice on the deck, and help with what to put in the sideboard would be very helpful.
