Omens, Fair and Ill

Hi all.

I'm working on a maybe-CCG (dunno format just yet; I like being able to give people everything at one time so NCCG isn't off the table) revolving around "reading" omens in play as a way to trigger sleeping cards (either in play or in your hand).

I'm just kind of running out of ideas for things that:

1) Are omens, of good, of ill, or of indeterminite goodness/illness based on other factors (e.g. a thunderstorm would be a BAD omen if you were on a flood plain, but a damn good one in the desert, perhaps...that's a terrible example, but I think you catch my meaning).

2) are actions you would take only if the "stars aligned" or weren't necessarily aligned.

I want/don't mind a mashed-up, anachronistic feel to things too-- sampling fantasy, parallel world, sci-fi, etc. from all sorts of time periods. I figured doing a big catch-all in the base set, then branching off (ala Munchkin, sorta) into more specific themes might be fun. Shit, MTG's doing loads of that these days.

Anything you give me to try out I'd be respectful of too-- even if it's metaphysical or religious-- the concept here is that something good/bad is on the horizon.

Thanks as always in advance...
