if you play on ghost deck you get an ankh on round 2 which you can copy the triboulet with.
You can also use the hex you start with to make all the copys polychrome
Triboulet round 1 from the jumbo arcana pack
Ankh from the shop in round 2
Brainstorm in round 5 shop
Invisible Joker (copies triboulet)
round 20 jumbo buffoon pack
Sock and Buskin round 31
Ecotoplasm on round 38.
I only played to like round 40 so there may be better stuff to find later on.
