Mechatron...how dare you? =P
That's my favorite mech. I made a huge post somewhere about him...
Here it is!
Here's my favorite build of all time...
Nerf-a-TRON (PVP Version)
FA: Arthurian Shield /Volt Strike
BA: Snowman Automatic / Venter
FS: Default/ Uniblaster /TNSEWP
BS: EDSP/ Graupel / Uniblaster
Activation: Just start with HD and BD, and use them whenever you want. Be sure to use data shift to.
I will do one section for each mod (Shield Bash, Volt Strike, Super Venter, Graupel) and a small note on some controversial mods. (Uniblaster FS, Uniblaster BS, TNSEWP)
I would recommend these changes:
Shield Bash & Snowman Automatic
Volt Strike & Snowman Automatic
Shield Bash & Super Venter
Choosing between EDSP and Graupel is a hard choice. EDSP if you are worried about running out of energy or are facing a mecha with healing, and Graupel is good for dealing high damage after nerfing, and the 10 turn DoT is very good. Uniblaster works pretty well too, but it is not as good as EDSP or Graupel.
Ok, this is a bit complicated, so here you are:
With Shield Bash, start with HD for +30 Defense, then use BD for -10 to -40 to Bonus for the rest of the battle. Next use Death Discs, for nerfing, then use Snowman Automatic. You use Snowman after because Death Discs will nerf defense so it doesn't miss. From there, just use whatever and respond to the situation. Keep using the BD whenever you can. Now, if you have complete control (Opponent has -70 Bonus due to Body) you can deactivate Data Shift, then use the HD for +30 Boost. After that, Death Discs will also give you another +30 Bonus and +30 Boost. This will help you beat healing build or Eidolons, and also ends the battle faster. Both EDSP and Graupel are good choices for this build, and each have their own advantages. Graupel will be a huge assets against healing due to it's DoTs and Increasing Damage. One interesing idea is to take out the opponent's EP with EDSP, because you have plenty of time to wait for the draining to finish. The extra Regen is great too, in case you are hit with a EP DoT or another EDSP. Uniblaster FS is an interesting addition to this build. You need Snowman Automatic and Shield Bash to make up for the lost nerfing from losing Death Discs, so this is the only build where it will work well. I think its a fairly good addition, it is great because the nerf lasts for 99 turns and also nerfs Boost. Read the note about it at the bottom. Uniblaster BS is also pretty interesting, I only recommend it if you plan to also use Uniblaster FS, because they work together really well.
With Volt Strike, use it first thing to disable the head. Its pretty much a free hit too, because it stuns right afterward. Now, do the usual HD, BD combo. Now do Death Discs, and then Snowman Automatic. From here, you can really do whatever is the smartest course of action. Keep using Volt Strike, and try to disable all enemy weapons. You are likely to get hit a few times because you are missing the +20 defense from Shield Bash, so be careful and make sure to nerf defense, because many PvP builds are nerfers who will lower your Bonus. I recommend EDSP if you use this build, because you are likely to be hit a bit more and might get hit by EDSP, which will mess up your energy unless you have your own to help you gain back all the lost energy. Uniblaster BS is also a decent choice, but you really have to hope you don't get hit by EDSP, or any strong EP DoTs. It does help a lot because you really do need more nerfing to make up for the lost defense from using Volt Strike over Shield Bash, and the fact that the nerfs last for 99 turns just make it better and better. You definitely shouldn't replace the FS with Uniblaster as well though, because Death Discs is a important nerfing tool that you really need to use for this build to work.
With Super Venter, you will want to start, once again, with the HD, BD, FS combo. Now the BA has some DoTs, a small nerf, and some healing. Its a great all around BA that can serve several purposes, from helping nerf, healing a bit, and working together with EDSP to drain the enemy EP. This is a more versitile build than the others and can do a lot of things pretty well. Remember to keep nerfing, but using the BA every once in a while gives you small heals and DoTs to help you in the battle. EDSP and Graupel are both good for this build, I think EDSP does slightly better because it combos well with the BA's EP DoT. The Graupel is also a good choice, because it lets you do lots of damage without having to shift back so you can get Death Disc and the Chipset's Boost buffs, and keep your defense up. The DoTs of Graupel are also amazing for wearing opponent's HP and EP down. It's quite slower than EDSP at EP Draining, but it does have it's advantages. This build is pretty good, and is very underestimated, because Venter doesn't seem to work well with this build, but it surprisingly does.
Note on Uniblaster FS: It is not quite as good as Death Discs I think personally, but 99 turn nerfs are pretty good. Especially since it also nerfs Boost. I think that Death Discs is better because it has a higher nerf that happens instantly, and also nerfs defense. The main thing is that Uniblaster takes 5 turns to reach the Bonus nerf that Death Discs gets to in 1, but feel free to use it if you prefer it. The good thing about it is that it gets stronger every time you use it, so it actually does some pretty good damage eventually. You probably need Shield Bash to make up or the lost nerfing from Death Discs, the extra nerfing from Death Discs is pretty important.
Note on TNSEWP: I am sort of debating over Death Discs or TNSWEP. Death Discs is much more reliable, and also has a larger Bonus nerf, at -30. The TNSEWP has at -50, 20 more than the -30 from Death Discs. It also has considerably higher damage. Sadly, it has a lower Bonus nerf, -20, and the nerfs are quite a bit less reliable. Not to mention you can't shift back and use Death Discs for the Boost and Bonus buff if you use TNSEWP. Overall, it depends on your preference.
Well, that was pretty lengthy wasn't it, I may add some more stuff sometime, but this seems to show off my favorite build fairly well. Well, that's all!
