Help with DB10 team

Sup, guys. I'm autoing db10 using this team: Verde (L), Veromos, Sigmarus, Bella and Megan. The problem is I'm doing around 80% and it's because Sig dies at Zaiross stage when he get targeted. I don't know what I could do to improve there.

Those are my mons stats:

Verdehile Swift/Blade 18.2k HP 182 spd 100% Crit Rate

Veromos Swift/Bkade 25k HP 204 Spd 64% ACC

Bella Violent/Energy 20k HP 180 Spd 70% ACC

Sigmarus Swift/Blade 13.5k HP 130 SPD 2100 ATK 76% Crit Rate 200% Crit Damage

Megan Swift/Guard 14k HP 834 DEF 194 SPD 63% ACC
