I get it easy almost with any team on auto till the last wave. Saske destroys half om my team with his mystery, Itachi gives chaos to anyone trying to cast anything and then gives combo that destroys other half of the team.....any suggestions?

I have my Neji in #1 position with 2000+ initiative and still can't interrupt Saske's mystery in the last wave...how is this possible?

That's what I'm thinking atm....I tried different teams with different interrupts, nothing works on Saske, he cast first anyway
