I was thinking of MB immunity team.

x-x-x

x - Itachi - Roshi

MB - Bee Thug - x

23213 Summon Big Cat

Round 2 Roshi starts against 4 units, no dodge ninjas you should do 31 hits that means both Itachi and Roshi will trigger their 30 hits chase ignite

or 24212 This one will finish your round with ur Main's paralysis enemy team.

I like second option more than 1st.

Bee's shield will give extra Roshi's survival.

---

This team is weak against who has Masked man, cos after itachi's turn he can immobile your main.

And no hard cc other than Paralysis and Ignite, but your immunity should cover it.

Round 3 as Immunity ends you should have done a lot of dmg already. Itachi starts fight and should have killed some unit(s).

Ultimate Uchiha RB team.

Madara - Shisui - x

Itachi (Anbu) - Susano Sasuke - x

Trigger all chase.

PS PB works but you know... Ultimate.
