They're all pretty interesting, but:

-Luck is insanely hard to render in the gameplay
-Door based teleportation / copycat are fun, but really rely on being deployed with other people. While that happens, both feel tricky to bring in -and still rely on a "core" power (think Prism) to really make this work / play. It also feels a bit light to be honest in door-based teleportation, that's just portals and probably not a main power, per se, but another "option". In something arcane, that would work nicely, but not as a primary.

My only concern is that the shadows theme is still something we already have too as Aura mentions.

Happy for you to PM me and I can help workshop something else. I think trying to avoid something we have. We have two "cosmic" heroes (arguably, already four), as mentioned two / three with light/dark / dark energy styled powers, so I'd like to see any future chars that come in have a slightly different theme. I think there's lots of other stuff to play around with, especially in the more arcane / technology / Batman-style vigilante side of things, which haven't at all been explored at all.

I might be tempted if you have an idea / char that you want to play with! PM me and I'm happy to take a look.
