[Startup] Self-supporting NC1-ZS

Concept

Startup cards only.
Priority 1. Always be running.
Priority 2. High Event deck that should have a self-sustaining economy.
Priority 3. High rewards for running central servers.

Advice wanted

I would like to get this deck down to 45 cards, but unsure what to cut. Open to advice. Originally had one less of each Icebreaker except Mayfly but also included a copy of Carmen, and an additional Mutual Favor.

Including 2 each of both Pennyshaver and Swift is probably overkill, given that only 1 can be in play at a time. So far I've only played the Pennyshaver, and it helped keep the economy ticking, so maybe the Swift cards should be the first two to get cut. Arguments for/against keeping them?

Are there any cards that I've missed, that would work better based on the concept?

Considering adding Harmony AR Therapy with all the events, as it potentially adds an additional copy of each of 5 different cards, or the cost of 1 card.
