Your spider team is just going to revolve around Sicia. For the stages that are green it'll be a bit less effective, but it'll still work.
- Sicia
- Visix (provoke / TM control)
- Astralon (non-red CC) / Drex (red CC)
- Coldheart (TM control)
- Apoth (non-red healing + speed up) / Minaya (red healing)
On auto it'll be a touch trickier, but it should work no problem. Just make sure CH is fast and has ~200 ACC. Her main goal is TM control, so you don't actually need to worry too much about CDMG / CRATE.
For Scarab King you have two options. You can build a team to full TM control the boss so you never get attacked, or you can build one that always has shields up. For DT normal, the former is usually easier:
- Metalshaper (fastest on the team, keeps everyone shielded)
- Coldheart (TM control)
- Visix (TM control)
- Rhazin (TM control)
- Kymar (resetter for CH / Rhazin TM control)
