RP Historic Glacier

This is what you get if you mix a fairly standard RP Glacier deck with Museum of History.

My ICE choices are based around having a good mix of fairly cheap ETR (Bako, Enigma), good facecheck/tax to make use of RPs ID ability (Ichi, Markus, Pup, Assassin, etc), and having decent parasite resistance (Bako and Lotus Field especially, and not having too much ice with low strength).

I'm pretty much in love with upgrades. I used to run double Ash, but I'm scared of the rise of Nexus Kate. Not sure if it is good enough to be a threat yet, but I'm being cautious.
Marcus Batty is almost as good, and costs no influence. It also comboes well with Ichi (and Assassin) allowing you to psi-game to trash programs fairly regularly. Crisium Grid helps against Legwork, Maker's Eye, and Account Siphon. It also reduces the impact of Datasucker, Medium, and Lamprey.

I like using Global Food to force the runner to score 4 agendas, while I sometimes only 3.
Fetal AI is a decent replacement for NAPD contract.
Braintrust and Philotic are actually quite good. In RP remotes are so annoying to check, making it easier than normal to bluff one out. People also often expect that an unadvanced card in a remote is an upgrade, so you can also bluff out agendas there.

Only done minimal testing so far, but am currently 3 wins out of 3 games on Jinteki.net (and my previous RP build was also doing very well). However I find that Jinteki.net tends to be full of playtesting/jank, especially on the runner side, so take those wins with a grain of salt.
