1) No you would need to copy it right there-Yea , I can creatively use this to suprise my opponent.
How would this go? What if I copy the technique used on me in the 2nd turn and I want to use the technique on the fourth turn? Possible?
-so i had to post the copy technique the turn I copy the tech?
-if I copy a technique used on me, can I at the same time defend from the same technique without breaking timeframe. As in. A wierd lightning is shot towards me my my opponent, I look into his eyes as he's performing the tech and copy the tech and as the lightning comes towards me, i defend against it accordingly, viable?
-certainly needs eye contact. Yes?
-it does not say anything about ce, so we can copy elemental ce?
-can we copy jutsus with no handseals?
2) And no just post this jutsu
3) You would be able to but I would say it would be like you perform the same jutsu to stop their jutsu
4) You need eye contact with the opponent but exactly the opponent's eye
5) NO to CEs
6) Yes as long as you have the same elemental affinity like your opponent
