Just to chip in, I found saddle is a weaker 4 outside of amazing combos. Maybe it should cost 3, but the idea is sound and it's a fun card to try to get to work. It has some great synergies: Ruins, Suburb, Rats, Necropolis, Chapel, Excess terminals, and more broadly cards you don't always want to play, Trashers and Discarders.
Oh, and I'm not a fan of having Jackpot use the journey token. I like to stick with a card until I realize it won't work. I'm not a fan of changing a perfectly good card to another perfectly good card. It gets you nowhere. Now if Jackpot is a perfectly good card, that remains to be seen.
