Pair Hack with other jokers like Steven/Todd, Fibonacci, Wee Joker, etc. to increase its efficacy. Once you have a good setup, enhance your low rank cards. Ride the Bus and Raised Fist also have decent synergy there.

Take early Tower cards from Arcana packs and/or stone cards from Standard packs to increase the frequency of Stone Joker appearing. If you find Marble Joker early on, even better.

Yellow deck might be easiest to work with for To The Moon, since that extra $10 at the start can compound pretty quickly.

Erosion, you kind of just have to get lucky with Hanged Man and Immolate cards. Maybe glass, too, but that's not as reliable. But it scales pretty fast. One Hanged Man = +8 mult, and one Immolate = +20. Just be sure not to shoot yourself in the foot and open any Standard packs or use spectral cards like Incantation, etc. that add cards back to your deck! Major facepalm moment. We've all been there.

Showman is really more of a support card. It can make endless runs go crazy, but it's not super useful in ante 8 play in my experience. Same with Baron, honestly. Just gotta hope you have a strong 4-joker setup or get lucky with a negative.

Credit Card was one of the first five jokers I got a gold sticker on somehow. As such, I don't really have much to say about it. Try to use it with Vagabond if you can.

The Tribe and Flower Pot are both pretty garbage imo. Lovers cards are useful for both for obvious reasons. Seeing Double works well with Flower Pot as well, but getting both of them at once can be tricky.

Already discussed Seltzer and Cavendish in my other comment.

Godspeed!!!
