Same as with the Plasma Deck except use your skips for as many vouchers as you can. Observatory is elusive and even hoarding double tags, I really struggled to get past Ante 12.

Skipped the first and second blinds of Ante 1 for a free Foil Constelation and opened the Bafoon Pack for an Astronomer. Optionally you can skipped the first and second blind of Ante 2 for the rare tag and a free Polychrome Satelite, but if you do this I recomend grabbing the +4 mult 6 of spades with the purple seal found in the booster pack. Perkeo can be found in the first Arcana Pack on Ante 3. The only Blueprint I could find was in the shop on Ante 11.
