I like these. I might also mesh 'em with the ideas I'm working on to make Action Points and Item Daily Uses into card-dependent rather than milestone-dependent things.
One set I'd add... since they're adding XP, it would seem to me to be perfectly reasonable to make some of the benefits contingent on narrating failure instead of success. For example, your skill-roll ones... in addition to the listed rewards you could hand out, say, Elite XP (2x Monster) for narrating an enteraining failure on the roll. [The roll must be one which the DM asked you to make, not one you initiated yourself. But this whole system is high-trust environments only, anyway, so that almost goes without saying.] Lets your highly skilled characters fail once in a while, for a legitimate OOC reason.
Edited to add: Tendrils, once I get my card set put together I'll post it here... my plan is to have AP / Item Daily / Milestone stuff all tied to draws from a deck, which give a baseline bonus A but also have an RP or player-contribution trigger ("If you brought snacks") to grant an additional effect or larger bonus. That might do some of what you want; a given card is aimed to be worth about half an action point, on average, which might not be a bad level of reward for your players.
