I have been running a Roshi-LM team the past week and it was quite fun, it requires Sasuke to be skillbooked/trialed for his 20 hit chase and 2x chidori spear at least:

Omoi x x
x x Roshi
Sasuke LM x

Talents: 2,4,1,1,3
Summon: Serpent chase, any mystery except Shiba

There are obviously counters to this team of course as implied by Zelgadis (blitz/immune removal//dodge), but I am just enjoying the dmg from Roshi and Sasuke's 30 chase almost every round. Ideally this is what should happen:

Round 1, Omoi standard triggers chase
Round 2, Roshi mystery triggers chase, LM generates chakra for Sasuke's barrier
Round 3, LM and Sasuke mystery
