It gives you a Perkeo and Brainstorm by Ante 2.
Use Sixth Sense to get Cryptid (had to wait a long time and had to make negative copies of all the other spectral cards until I got Cryptid, so make sure you have plenty of 6s).
Showman gives a lot of Brainstorms, so you might need to save up money for rerolls for Blueprints to have the balance.
Could possibly be a Round 118 Seed, but I saved up a bunch of double tags from Diet Colas and used the voucher tag to get a lot of decent vouchers early on.
