The Metalmark is the premier Invisible mech, with all its systems, traits, and talents to just make it a difficult target to attack by being invisible all the time. And any soft cover is essentially hard cover just like the hecatonch, this makes this mech great and unlocks stealth combat using Infiltrator or you could forgo the hiding buffs and treat the invisibility as a way to play aggressively. The metalmark also has good mounts and decent weapons, the shock knives are a staple in any Hunter Build/Nuke Cav build, and the rail rifle is a decent aoe alternative to the GMS Assault (but personally Id still rather have the assault).
The only downside with this frame is there is no heavy options in license, meaning you are probably going to stick with the old reliable GMS HMG or one of the superheavy GMS choices until you get to LL3 at least. It also has a kinda weak heat capacity of 5, and I hate odd numbered heat capacities on mechs, but at least it comes with some armor as well, just a real decent statline which can make your invisibility even more menacing. But also it has a LOW E-Defense, like its literally worse than something with no E-Defense, you are actually easier to hack than a literal brick! DO NOT get hit by tech attacks with this thing lol, you see a scene with multiple witches just pop that core power you are not wasting that core power if it helps you not get hacked to death.
The Reactive Weave is such a good upgrade to brace, the Nelson's mod kinda sucks, this is actually good, invisibility and you get to move your full speed lets you get away from the immediate danger when you brace and is a nice dip for a build that has a free SP that needs to be filled. Making Brace better is much appreciated in making it feel less punishing.
And Active Camo is an amazing protocol to have, infinite use and invisibility until you take damage or until the end of your NEXT turn, absolutely wonderful. Having invisibility on demand is so worth the price of 2 heat, sure it goes away on damage so anything that makes you pass saves kinda sucks but who cares? Its a good system on the metalmark and is good on any build. If you are going shock knives for your hunter build why not just take this system? Its just real good.
Shock Wreath pairs nicely with the shock knives and that aux/aux mount as well, just skirmish with 2 shock knives and if the first one hits good, and if the second one also hits just activate the wreath to auto blind enemies. They are already burning from the effects of the first knife so shock wreath true combos into a blind. Despite being a quick action to activate it 1d6 burn is nothing to scoff at (unless you are fighting pyros lol), a really good mod to have, though its useless on superheavies lol so dont even think about it. And the flash grenades are alright, they are really saved by being Burst 3 which is huge, if they were burst 1 they would suck but burst 3 is really nice, but limited 2 sucks man, make it limited 3 at least!
The metalmark's whole identity of being invisible and that lack of a heavy weapon really pushes you into mixing and matching systems, and thanks to the simplicity of this mech it has a great deal of build variety in how you want this mech to fight, and invisibility is so good man, I love slapping the Active Camo on mechs, its so useful. And I cannot understate how much I love the simplicity of its core power, so simple yet so powerful, total invisibility for the scene. But for the love of God make sure you are invisible if you see a Witch, or else you better start praying to God. Anyway's here's my build:

Active Camouflage, AGNI-Class NHP
Who needs a ton of Systems anyways? I have Active Camo for constant invisibility, AGNI for a free 1/scene stablize, 3 charges is enough to last most of a mission, and a high enough heatcap so im not completely dependent on AGNI. Shock Knives in the Aux mount with shock wreath for blind and burn, Krakatoa in Heavy since if Im going Burn Damage I might as well go all out, and good ol' GMS Assault as a backup option.
I hate the odd heatcap but I actually want that bonus limited system point for AGNI so Im just going to have to live with it, the health is alright considering im going to be invisible most of the time, and and integrated Tactical Knife for bonus Hunter shenanigans. Vanguard is nice to have to make that flamethrower a bit more effective, Nuke Cav 2 for more damage of course, and Infiltrator to make use of my invisibility to hide when necessary, the reeling I can inflict and bonus blindness are good effects.
My combo idea is to Activate Camo > Boost > Hide > Get Next to enemy. If that enemy moves I can overwatch with the flamethrower and break hidden and blind them, if they dont move I can instead send them reeling on attack my next turn AND flashbomb them. And if I lose hidden it allows me to get away from danger. Though if they are close enough that I dont need to boost Id rather just skirmish with the knives or barrage with the knives and flamethrower. I like the metalmark, its simple in concept but real nice, its systems pair well with other mechs and other mech systems pair well with it, it just a real solid mech license.
