I've just picked up this deck, and have been going over the sideboard choices. I built my list referencing the discussion from this thread and the most recent Top 16 list (15th Place from SCG Providence)

I'm getting ready to take it to a local event next week, and I think I'm happy with most of my choices, except for one. The SCG list I linked plays a Bloodghast in the sideboard, which at first glance seems nice against removal heavy decks, but I've been thinking a Grave Titan might be a better fight for the slot. Am I missing anything with that assessment?
