I'll come out and admit it: I made the jumpchain for New Capenna in a day solely because my friend wanted a New Capenna jump. It wasn't a serious project, so I cut some corners. That's on me.

>If you can't make a drop in line, allow any background to be drop in
To be honest I forgot I could do this. It's an easy fix, so I'll get it shined up for the next version.
>allow anyone to pay to be an angel
I wanted to keep angels restricted to unaffiliated groups because being an angel in New Capenna should have some difficulties tied to it. If people just want an angel altform, there are better jumps for that. If you're getting it from New Capenna, you should struggle for it.
>the other races (besides sphinx) aren't worth 100CP and shouldn't be background exclusive
The reason they are is because those are the tribes associated with each family. There is definitely a powergap between sphinxes and the other races, even mechanically, but it feels fitting enough.
>but "their better" how? Socially?
To be honest I just had no idea how to convert this card into a perk.
>how do those work if you draw them? Does learning a spell this way actually teach me (a new color of) magic if I don't have it from my build?
So the idea in the MTG card game is that you, the player, are a planeswalker and your deck is your spellbook. Now obviously, spells like Lightning Bolt are easy enough to understand in terms of how a planeswalker would cast it as a spell, but not all of them are. Like the 'sudden betrayal' you mention, it's unclear if casting a spell like that would fall under something like mind control, or forced misfortune, or just a lightning bolt flavoured like betrayal.
So basically, I dunno. Yeah that's a shitty answer, I know, but it's (potentially) fun to think about how Jumper would cast something like that if it's in their spellbook (but probably not on par with their perks and spells-by-fiat.
