I can't get a win
Got a joker that multis face cards
Got a joker all cards are treated as face cards
Boss: all face cards are debuffed
A few tips from a massive noob (have only won with blue and red decks):
Win the first round with your first hand so you have 10 gold day one.
Need to take any anyway decent joker(s) in antes 1 and 2 - you need them to survive but also fast clears to get more money. You can sell them later on. Likewise buying jokers that are good for only a few rounds (banana) is also ok if you have the space imo, so you can clear super fast and you have time to build up your joker/planet cards.
Try to get at least one gold making Joker in antes 2 and/or 3 to set up your economy, even if it means buying a gold making joker for just one ante, you'd be surprised how quickly your economy can snowball and set you up for later rounds.
To get wins you need planet cards for your 2-3 hand types that synergise with your jokers, you need good multi jokers (obviously) but you also need multiplier and polychrome cards. Basically antes 4-6 you are building up your planet cards, different types of jokers with mults and multipliers along with polychrome and synergizing as best as possible. It's doable IF you have a decent economy.
ALWAYS look ahead at what the big boss blind's special does, so you have a couple of rounds to plan accordingly.
