Did you draw the telescope by hand or use a rendering program? It looks really good!
I'm not sure if allowing hand reveal to all decks is a great idea (for the upped). I think it should probably still cost
quanta...
Other than that though, it seems like a nice card. Very low key, but possibly quite useful in the right deck types...
One neat addition would be to allow the telescopes to shuffle the opponent's hand. E.g. randomly shift the locations of the cards in their hand.
This would have no real effect on the opponent's gameplay, but would allow the user to see the opponents card more easily.
This could serve as a good way to distinguish the upped and unupped versions as well.
