A few item specific combos I've seen Nage do.
You can combo into 5D in the corner after throwing a poison bottle for okizeme. Combo into knockdown, item throw oki (poison), 2K (2nd hit), 5H (2 hits), 5D, homing dash, j. S, j. H, 6H, pogo, P, going my way. The game said it does 124 on Sol but it probably does more than that if you add in the poison.
If you throw a black hole midscreen you can do 2K, jump back cancel, j. P, j. K, j. P, j. H, 5K, 2H, pogo, going my way on standing characters. This combo is obviously easier on taller characters and doesn't work on May, at least I couldn't find a way to do it. It does 114 damage on Sol.
And in the corner you can do blocked 2K (1 hit), item throw (bomb), mettakiri, 5P, 5S, 214P, wall crumple, 236S, P, Going my way. The bomb will hit easier with Faust being further away from the corner and the opponent being closer. Does 148 damage on Sol.
