If you want 1 ninja that counters sosp (not whole lineups designed to counter sosp teams) its 4th raikage with breakthrough mystery and egf kakuzu with x2 standard passive book. We are talking about 1v1 scenarios. Both outheal his heal, as well as are able to do significant damage in 1v1, asuming both positions are equal in power. Raikage should actually demolish stronger sosp.
