I used the same lineup mentioned in OP with success for a long time in a slightly different order and using DF.
namely,
MC tobi oboro
kakashi neji (kakashiclone)

The key to using it effectively lied in when and how you used neji's mystery. I would use it most commonly on their prio 1 ninja at the end of round 1 (after the target and any healers have acted to make acu * through round 2).
Using neji like this you can get tobi's mystery off regardless of any initiative deficit.
After a while I swapped kakashi out for Orochimaru and moved him to the front line. Both orochimaru and tobi's mystery had certain hit (although it's not shown in tobi's description) so it was a good counter when most of the top players were also running Tobi.
