I feel these links are integral to the discussion. I can't wrap my head around the Jemison combo without looking it up every freaking time, and promptly forgetting.
Jemison Astronautics: Sacrifice. Audacity. Success.
Whenever you forfeit an agenda, place 1 advancement token on a card and 1 additional token for each agenda point the agenda was worth.
As an additional cost to rez Oberth Protocol, forfeit an agenda.
The first time you advance a card in or protecting this server each turn, place an additional advancement token on it.
If I get this right, assuming these imo common scenarios (Hostile scored, Oberth already installed unrezzed in remote, agenda in hand), you can install agenda, rez Oberth+forfeit (two counters from Jemison), advance (1 additional from Oberth), and advance to score a 5/3. Sick. If Oberth sticks next turn, you can score 3 cost agenda from hand, no forfeiting required (Atlas, utility 3/1s).
Also, get this. If, instead of scoring a 5/3 with the above combo, you could score an Atlas with 2 counters. This could directly lead into an Atlastrain if Oberth sticks, which it very well could in a rush style strategy.
