4 polychrome jokers. 1 from skip, 1 from pack, 2 from wheel of fortune.

Order was kinda polychrome joker from skip -> wheel of fortune polychroming another -> flower pot polychrome from joker pack in the shop (the one with 4 jokers in it) -> ~in ante 7 wheel of fortune polychromes another joker.

My strategy: ceremonical dagger + polycromed jolly joker + polychromed rocket (both from 1 ante, but can't remember what polychromed by skip, and what polychromed by wheel) + polychromed flower pot (from pack) + in ante 7 I got supernova, that were polychromed by wheel.
