Was asked to give a judgment.
Ya he's able to perform the Chidori Nagashi while paralyzed, it requires no handseals, and works well specially against the temporary body paralysis one, you release chakra into him or around him in order for him to be restricted with the chakra, so his lightning chakra overwhelms the chakra you are restricting him with and frees him in the process.
One thing that i noticed though, while using the Underground Fish Projection technique, your body cells basically are merged with the ground atoms, so you have to constantly release portion of earth chakra in order to keep your body in the merging state which it undergoes during the technique's activation, you can use only Earth techniques up to B-rank while using the underground fish projection and currently merging with the ground, any other techniques you use while you are merging will cause your atoms to split apart from each other, basically ripping your body to shreds instantly, just wanted to post this for future reference to both of you.
I also don't agree with PridentPush's counter to the Exploding Flame Crater technique, apart from the fact that you reacted as you saw the Lava coming at you which would put you at an even greater danger, you used a C-rank technique to counter an A-rank one? the wall would be smashed through as soon as it forms, then you wouldn't get enough time to perform your wind and evade the Lava, not to mention the fact that you changed your chakra nature into wind while using the Underground Fish Projection technique and merging with the ground, which means instant death, however since you guys continued i won't stop the match here, it's all about having fun, i'm simply addressing your mistakes so you can learn from them.
One last thing i need to add, being paralyzed by a technique is whole a lot different than being paralyzed by a lightning shock, by a technique you can just overwhelm the chakra that's paralyzing you and free yourself and also works in case of genjutsu paralysis, you just can't move so you can't use a technique that requires handseals, but being paralyzed by lightning means that your nervous system is temporarily shut down, so you can't utilize your chakra circularity system for a short period of time, in other words you can't perform any technique that requires your chakra, the time it takes to escape the paralysis varies according to the power of the shock.
