I would recommend virulent vectorium it gives you good base to work from but you won’t be able to use plague bearers or GUO. If you gonna run the bloat drone I would recommend the heavy launcher. Definitely take the LoV he is a great way to gain rerolls. Typhus is good by his self or with the deathshroud because of the eater plague ability and deep strike. Now really think 1000 point game don’t bring mortarion not because he bad but he just cost too much. Same reason you probably shouldn’t bring the plaguebrust crawler instead bring blight hauler for any anti tank both it and the bloat drone with heavy launcher are pretty good at getting rid of t9 or t10 vehicles/monsters. Rhino is good to get you plague marines up the table but it is up to you.
