Inti is fine in the current meta, but it needs to be backed with Atman or Lady. I prefer Atman, it solves multiple issues with one card slot. You don't need a perfect rig. Snowball is garbage, don't play it. Paying 7 the first time you encounter an inner Vanilla is not what you want.
I think it's a huge mistake to go below 3 Refractors. You want it early and you don't want to pay 3 for it. Cutting SMCs to 2 is better. The only way I can see going to less than 3 is to replace up to 3 of them with Houdini - this depends a lot on your meta.
Mirror is totally not worth it. You are paying 2c over Astrolabe for a pretty useless ability and an extra MU that you don't need. Labe is so good vs horizontal, especially Russian NEH. Also on the note of MU, there is no reason to play Scrubber over Paricia. Paricia is +2c the turn you install it, and it can be tutored in a pinch for +-0. The assets only limitation is mostly a non-issue, and in matchups where you need it MU is also not an issue because often your rig is Refractor and 1 other breaker.
I think Temujin works better in Kit that it does in any other shaper because of her ability to make single-iced servers negligible - and don't give me that 1 run per turn crap, that's just false these days when corps are mostly on gearcheck. 1 facecheck per turn is more accurate. HQ is a good Temujin target early, especially if it's open turn 1. It's basically pseudo HQ pressure without spending additional influence, and you can force early double icing with it. Archives is not great unless you really need the money, or are also on Patron or something. Once RDIs are down then you go for R&D.
My win rate with Kit increased considerably with Temujin - it allows you to generate enough money to stay ahead in money race matchups and trash key assets vs horizontal (provided that the rest of your econ package isn't lacking).
My influence currently is: 3x Temujin, 2x Clone, 1x Clot.
I haven't yet decided what to cut for Mercur, but I'm leaning towards cutting Cloaks instead of Casts.
