Just had one of my best runs.
Perkeo, Fortune Teller, Constellation, Blueprint, Brainstorm.
Did this before each round to copy x3, then:
Constellation, Perkeo, Fortune Teller, Blueprint, Brainstorm.
For the game.
Constellation got up to like 15x. All cards had a bonus from Wheel.
Perkeo copied a bunch of Temperance to get me up to like 250. Full house got up to 50+, then into flush five. Copied a bunch of the Specral cards and got both lucky, red seal, and polychrome on an ace. Copied a bunch of deaths with Perkeo and turned most of my deck into that ace.
I passed a couple of negative giving Spectrals early which I should have taken, got a crap negative (+15 mult at 0 discards) early and used it to get out of the all cards debuffed boss, then the only other I found was +1 discard (good utility, but not going to carry).
Only got to 13 in the end. I got a bit greedy copying my Ace instead of copying my Eris. Which I should have done as I had the voucher that gives xmult for each planet card.
Still, was so much fun!
