I use a team like this. It's not bad, triggers a very high combo rating, and also deals with poison damage and burns. Lacking good healing support, so unless you're strong af or confident to not use a healer, you can try this.

Combo#1 : Karin's mystery > Main's attack > Wind style vacc barrage (10 hit) > Sasuke's Fire chase (10 hit) > Triggering karin's poison again.

Combo#2: Same as 1, except after fire chase, triggers into karin's High front, into gaara's sand burial.

The other combos are either small and connected well, or ones that I can't remember by heart. Can update if I see anything else interesting with the set.

Wouldn't know, but I can test out tomorrow or something. it's cause karin's mystery lets her rack up combos naturally, then either my main or gaara moving right afterwards.
