Take out  {Arrest} for an  {Obzedat, Ghost Council}.

4 sorin's is a bit much, maybe drop to 3 to make room for something else?

Ok so here's what I'm thinking drop 2 plains 2 swamp for the 4 new shock lands then I'm not sure for the ghost council card, maybe go with what he said and drop the arrest.

4 sorin's is a bit much, maybe drop to 3 to make room for something else?

I used to really like having 4 sorins, he was a great decoy for this deck, throw him out there, get the emblem, opponent has 2 choices leave him and let me make more tokens or kill him leaving me a free turn basically to set up other stuff and with 4 in a deck it's almost guaranteed play. although yes sometimes i had to mulligan for drawing too many
