Second Arcana Pack of Ante 1 (in the second shop of Ante 1) contains a Triboulet, there is a blueprint several rolls into Ante 5 (after taking the heiroglyph voucher, haven't scouted that much), first Arcana Pack of Ante 9 has a Perkeo. Wraiths are all bait. Take Voucher Skips and all vouchers. Early on there are Spectral Packs with Gold Seals, and Arcana Packs with magicians and devils, and there are hanging chads, mail in rebates, and golden tickets for econ. This occurs on any deck, but Ghost Deck has spectral cards in the shop, making it easier to aquire a spectral card to copy with Perkeo. Around the time you gat Perkeo, there is a temperance that can be copied for a lot of money.
