I'm actually a fan of the thralls, so I'd say they should be back by about 2-3 of them. The cutthroats do look nice in this deck giving it a bit of aristocrat feel. Evolutionary Leap's good, but I think it's better to draw something you will/might need like a land or a sorcery/instant than a creature that you can't really use. It does work well in some ways.

Alright.If I were to dump a couple of thralls back in, maybe dial back on each of the husk and cutthroat?

I am having a really hard time determinig what to toss for the altar's reap. Abzan ascendancy pulled a lot of weight every time it came out. I would like to see more of secure the wastes before i toss that one.

The removal suite is hard to pick apart.
