I don't really see why I need a sac outlet. Maybe I'm missing something.

You use a sac outlet to trigger  {Blood Artist} ability. Like I said by having that sac outlet. Not only are you pumping up one of your creatures for an attack or for a block but your proactively using your  {Blood Artist} trigger. A mini combo if you will

I understand that but I don't understand why I need it in this deck perse.

[brybry723]

You have  {Sorin, Lord of Innistrad} to make tokens every turn so you have something to sac every turn. Also it's a quick and easy way to get your  {Tragic Slip} to give -13/-13 instead of -1/-1. Just a thought. You were looking for some ideas so that was just one I had

[Mothaelon]

Right. But sorins tokens are mainly for my bloodline keeper, or I just go for emblems so I can push harder with my captains and first strike.
