I think you're trying to do way too many things with this, even for a Sam deck. Right now it's not really a FBTN/Sam deck, it's a Sam deck with Beneniah and Captain of the Host in it. If you want to lean more towards FBTN (my personal favorite), take out most of the teal, purple, and Jacob, and focus more on banding (Israelite Archer [if you're dedicated to Captain, who I don't like in a Sam/FBTNB], Heldai, etc). If you want to lean more towards NOT FBTN, well I'm in no position to give advice. However, as it stands, I think the deck is too bloated, and you can manage to make it more focused and streamlined while cutting down to 51 or 52 quite easily.
