Flagstones of Trokair doesn't seem to do much unless you're running a shell where you can destroy and recur it to ramp your mana (e.g. KCI Eggs, Naya Loam, etc.).
Elspeth is better than either Sorin, IMO. Just go with three Elspeth if you want walkers. Re: disruption, I think replacing your Midnight Hauntings with Thoughtseize/Inquisition/whatever would be a pretty good move. It's definitely the weakest of your token producers.
The thing about Rest in Peace in the board is that it neuters your own Lingering Souls. Since you're in black already you might want to consider replacing them with Leyline of the Void for graveyard hate or Leyline of Sanctity to avoid being raced by RDW. I can't say I've played with Lingering Souls extensively, so maybe it works out just fine. Plus, if you're in white, Stony Silence is a must-have sideboard card. Utter End is kind of slow for spot removal and Oblivion Ring/Banishing Light/Hero's Downfall hit most of the stuff you should worry about anyway.
I'm not quite sure why you're running Altar of the Brood. It seems to me that this deck is primarily the tried-and-true token beatdown deck and randomly throwing in 3 slots for mill doesn't seem to be doing much for you. Midnight Haunting is okay, but I think sacrificing the flying for a less mana-intensive version in the form of Raise the Alarm is a better choice. Rootborn Defenses seems strictly worse than Brave the Elements.
