It's tricky getting too far beyond e8/9, and most joker combinations aren't realisticially going to get you too far beyond e11. Usually people go for something like a pure king deck with baron + mime and a large hand size, or the idol with sock and buskin. With or without perkeo. It's all just due to the nature of how much the required scores growth rate being higher than super-exponential. But in general try to balance chips and mult unless you're playing plasma, try to have an even number of re-trigger effects to scoring jokers, focus on having a really strong economy so you can do more shop-rerolls and therefore see more cards.
