Clone Squad for Arena

Cody lead is only for 2 reasons, protecting Cody himself and giving clone sarge more crit chance, without clone sarge you'd prolly do better to run Rex lead. Furthermore I cannot recommend that you gear clone sarge enough... He is a God in raids I usually score 4-5 million in one attempt and he's responsible for 2.3 million of it, plus he opens your arena battle by sweeping down the enemy teams turn meter and almost all thier protection bars right off the bat, and getting offence up. He's also up there in the top 3 dps due to his speed and TM gains. While you're gearing him (as note he dosent truly shine till omega passive and basic) I'd run Rex lead with RG
My current lineup is
Rex
Sarge
5555
Echo
RG and I'm holding top 20

P.S. seriously get clone sarge up to max ASAP
