Deceit 2: Soulbound + Seer = Trust 

If you ever choose The Soulbound, Soulbound the Seer.
If you Soulbound the Seer, the Innocent have no choice but to trust you.
Allow the Innocent numbers to go down a bit and then eliminate the infected.
Go into final showdown and eliminate the remaining Innocent.
My Seer was not the best in this match, but it was still one of the most fun matches I have had in this game.
The infected played very well in this match.
This was my 1st ever attempt at using Soulbound on the Seer. I will perfect this tactic in due time.
