Help me get the gears turning again

[Nova_chron]

Hey fellow brothers and cousins of the blood. As the title says I'm trying to get myself back into gear so to speak I'm wanting to build a flesh tearers army.(will flip between chapter BA or FT based on do I want Seth in the list) I've got a mishmash of minis including ten intercessors, all the characters from DV, primaris librarian, and then a motley crew of tactical marines, assault marines, a librarian dread, storm raven, and an assortment of tanks including a siccaran I'm looking for some ideas of a strong core to build out from. What have you guys found to be best as a core force that you can almost use like a Lego base to add other groups onto I tend to play in the 1850-2500 points value range.

Do you have heavy weapons for Tactical? Having a battalion is ideal for Command Points so having two supporting Tactical (in the absence of Scouts) and the Intercessors along with two characters will start you off fine.

I have all heavy options available except grav and I think I can build more. What have you found works best to add to that initial block I'm kinda trying to go with a redemption of the FT theme. So less death company and more combined arms lists keep me engaged in the games more
