I don't find shikamaru Chunin fitting that well on 2nd team. Kushina only hits non-dodgeable ninjas, and usually kill them in 1-3 rounds. I suggest to put Iruka with Y+1 passive instead. In the first team, I don't really see ligthning main worth it, i would prefer the tanky Earth :)

Well gaara+kushina is way cancer combo because gaara is really hard to kill and he keeps applying shield on kushina but he's only good when he's full broken otherwise he's * but he can gets you wins if it's a 10 round battle cuz of all the shields and he's pretty tanky which makes him hard to kill so you win by having more hp but i prefer going with fire main instead of light main yes you get the leech but light main will prob die in round 2 or 3 fire is better because if they control your gaara you can remove the control+you got reflect and you can get resets if your kushina will kill with her mystery which is pretty useful as well and bani chakra which gives gaara more resistance cuz of his passive which makes him harder to kill

2nd team: it's pretty good but you can't expect them to survive more then 5rounds expect kushina even if you go earth main but idk if you know if you got high control and you can control pos 1 with your itachi then you can just use kushina to remove immunity and then edo itachi on that immune ninja and the dream status will carry on until they get more then 30 chakra then use healing or use something to remove the buff if they don't have that then dream status will carry on for 2 rounds and in that much time you can do really good amount of damage

Kushina hits ninjas with lowest life it doesn't matter if they are dodgeble ninjas or non dodegable
