A.) Sharigan does not increase ones reaction time as well as the fact that we were at a long distance from one another in the first place and him and his clones being completely unaware of my location. I.E. He cannot see underground especially at long range and the two of us being on two completely separate Plateau's so that brings up
I never said I did see you underground. I don't need to since I see you as you start to rise from your plateau. Remember, I said that I and my clones are cautious and are looking at the ground, checking the area ect so were very alert to noticing you. Even looking between the spears as they could still see between them. Since seriously, me and 2 clones with 3T. I'm pretty sure I could see i between them as there are spaces in between them and they are constantly moving through the air. Not too mention the spear isn't that big at all, so if it splits into 100, of course they would be smaller as it's simple division, they would be 100X smaller actually. So if about half of them are hitting the water. That leaves 25 for the front of the plateau and 25 for the top that are spread out, and with catious clones including my self carefully checking the area for you with 3T active to track any movement and to see the spears move in a more slower motion to have more time in between spaces to see which wouldn't be needed really. That just adds to that I could still see you. Not too mention that for it to hit the water, front of the plateau and the top, that means it's shot at an angle meaning even less spears at the top. Also, they hadn't reached you yet and they were small spears, 100X smaller than a normal false darkness spear, so of course I could see you. Almost like shooting 25 really long arrows at you, even 50, I'd still be able to see you because they're that small and spread out. Now, if I didn't see you from that (which it's obvious I would be able to at least know you came out of the ground) you still went into the air which means, I can see you perfectly. You go into the air. I notice you. You do handseals to defend from the spears as a clone would be doing the handseals for the earth tech. You would finish your seals first due to you needing one less handseal and perform your technique. Tho, a handseal can be done in under a second and as the jutsu says it makes the jaws instantly and slams shut. However, your technique is much, much more larger scale than mine and so it would take longer for you to perform it, blowing out all the wind/fire. But you see, my earth tech can be created instantly, is B rank so it's naturally faster than your S rank wind/fire blast. You still wouldn't have time to finish performing that technique and then use nagashi before that earth devours you.
B.) There would be more than enough time for me to do so seeing as he would need to infuse his chakra into the ground, it go down threw his plateau and up into my own plateau at a long range. THUS not making his move happen "instantly" which in the end would give me I would hazard to guess would take at the minimum of 5-8 seconds therefore giving me more than enough time to easily jump out of the ground and fire off 2 different blasts. Which I will bring in the argument used against me earlier in this match
Just like how you need to gather the chakra of two different elemnts, infuse both jutsus and use them together? I even had a head start for the earth tech tho you say it's not fast enough?
Also, if you're looking for technicalities
*when my clones get crushed I gain the knowledge that they were crushed so I refrain from going deep into my plateau but instead I go back to the surface seeing as I would know that you would also send electricity throughout your plateau and into the water below, and would also figure on attacking my plateau due to you not seeing me. As I jump out of the ground and see your False Darkness Spear(s) are heading for me and my plateau I use Wind and Fire Blast Technique*
You said that you would know that I would do the lightning technique and even knew how I would use it. But, you were underground and had no way of knowing and your clones died before that happened so they can't give you an idea for it either. So you would have had no way of knowing I would use a lightning jutsu nor would you have any reason to think I think you're underground. More or less that you knew which tech it was and how I would use it and was specific about it. Yet you were underground and had no way of knowing that I even think you're underground. Therefor you would have never came out of the ground and would end up in my swamp. You're not psychic, you would have had no way of knowing I would even attack you, but you said that I would send a lightning attack through the ground and even said that I would make it hit the water between our plateau's. You had no way of knowing that I thought you were underground at all. So, your reason for going above ground wasn't at all proper. If you could predict such moves then you would have never went underground in the first place. Your clones were even destroyed before you went underground. Basically, that only leads me to believe that you couldn't think of a way out of that move so you made a reason to get out of it that wasn't proper.
For the rest I'm going to just let Izuna explain.
@Gobi, Kakazu's elemental masks allowed him to use elements as if it was his affinity and was able to use jutsu with/o handseals with them.

Kakuzu's animal masks, which resembled those of ANBU, contained his spare hearts. If he took use of the heart for himself, the corresponding mask would shatter upon the creature's reentry into Kakuzu's body.
Earth mask: This heart had an earth-affinity, and took on the shape of a demonic, beaked bipedal. It allowed Kakuzu to use Earth Release: Earth Spear. In the anime, even though this mask was destroyed, Kakuzu was still able to use the Earth Spear technique, though it only hardened his arm.
Fire mask: This heart had a fire-affinity, and took on the shape of a demonic tiger. It could use Fire Release: Intelligent Hard Work. This mask could also unite with the Wind mask to launch a fire-wind dual strike that was near unstoppable.
Lightning mask: This heart had a lightning-affinity, and took on the shape of some sort of deformed bipedal. It could use Lightning Release: False Darkness.
Wind mask: This heart had a wind-affinity, and took on a strange four-legged body with thin wings. It could use Wind Release: Pressure Damage. It could unite with the Fire mask to launch a fire-wind dual strike that was near unstoppable.
