Starting chaos army
Been playing tyranids for about 7 months and am about to start a chaos army. i was given some and will convert some from the deathstorm box. I prefer nurgle and think my first addition will be Typhus. was wondering with the current list what i should load out my army with. also what should be my next additions I am also considering conversions. as stated i played tyranids so space marine rules in general i am new to and do not fully know how to use them to my full advantage. I currently have.
1 Chaos lord in terminator armor
7 csm ( will convert to plague)
1 hell brute
i also have the following and am open to any conversion ideas
1 captain karlean
1 death company dread naught
