Regarding the decklists:
Kate should be played as listed, or with minimal change.
I feel it wants a 2nd Escher, and maybe 1-2 Test Run. Escher midgame is so backbreaking that I think you need 2 to make it so that you can get it more reliably. I've had games where I was heading towards a loss, vs things like a Weyland with rezzed Archers, and drew Escher and won as a result.
Regarding what to cut, you could cut a Dirty Laundry or two, and maybe an infiltration (but only in a meta where you thought you wouldnt need it as much).
Regarding the Andromeda list:
- It needs another Crypsis.
- It needs a Ninja. But it should keep the 1 Mimic.
There are choices to make regarding resources, and I feel that the correct option is to either play 1 Pro Contacts, OR to play John Masanori(s), but not both. The John Masanori plan is more likely to accept tags. The Pro Contact plan wants to avoid them.
John Masanori is kindof feast or famine. When you can get in, he is an IMMENSE beating. Makes your first run ALSO like a Pro Contacts.
You generally shouldnt play him right away however. Playing him is kindof an art, and requires practice. (Ive screwed it up multiple times already, and lead to painful games, yet still won them, because...Andromeda!)
You generally want to play him after you get initial ice rezzed, and you know you can safely hit things, or when your rig is developed.
I am unsure about Hostage. I would definitely play 2-3 Hostages if I was trying Pro Contacts, but I'm not convinced thats the best plan. Its better to draw your resource than Hostage for it. I'd rather just draw my Kati, so I think a minimum of 2 Kati is correct, and maybe 3 is correct. It might simply be best to play like 3 Kati, 2 John Masanori, 0 Hostage. Alternately, something like 2 Kati 1 John 1 Hostage, or something.
For a deck using Pro Contacts, I'd go 3 Kati, 1 Pro Contacts, ~2 Hostage, and no John Masanori, and probably 1 Same Old Thing.
Finally, you could make the Data Leak/John Masanori/Crash Space deck. But I think its probably weaker. If Jackson didnt exist, this would be pretty awesome, but he does. If you do run that combo, you need to not just do it early on and not build up, because theyll ice archive, stop you from getting to it, and get a Jackson. You'll instead want to use this later after a normal opening and development.
