Ok, Nereus, I want you to start out with an ice Shard to Raven. Then since both of your opponents are going to gang up on you, so do your best to protect against both of the attacks. Finally, finish with whirlpool to raven if he isn't trapped in the rock tomb and Hidden power to Matt if Raven is trapped.
Ziva, I want you to start with rock tomb to Raven. Follow that up with a Drain Punch to Matt. Then, I want you to finish with force palm to Matt.
Nereus: Ice Shard (Raven) ~ Protect ~ Whirlpool (Raven)/Hidden Power (Matt)
Ziva: Rock Tomb (Raven) ~ Drain Punch (Matt) ~ Force Palm (Matt)
