In the rules, I have a couple questions/comments:
1. You should probably rename "events" because of actual Events now.
I guess you're right, having a capital "E" for Events isn't enough. Not sure what's good alternative though. "Effect" doesn't really work.
2. Where's the rule that simultaneous things all affecting you are chosen?
Do you mean the rule that you decide in which order to resolve simultaneous things that affect you? That is in several rulebooks.
Edit: Oh, do you mean where I put it? It's there, under "Resolving events".
3. I'm not sure your version of the lose track rule is correct. It's not "if a card isn't in the expected place", it's "if a card has been moved since this card originally interacted with it" (or something like that). This is important for things like Princed Reserves.
Yeah, I know. I think Princed Reserves is the only example we know of. So now it's more complicated. I was avoiding it. But actually I think I have a good way to phrase it now.
Also, I just randomly saw that Band of Misfits seems to say that it's that card for forever, instead of until it leaves play.
No, it has a state timer.
