The first ability here is a bit tricky in the rules. I think it would need to be phrased as:

": Reveal the top card of your library. Play with that card revealed for as long as it's the top card of your library."

Then the second one should go ": If the top card of your library is revealed, ..."

Thanks for the help. Because I'm so rusty, I'm going to need a lot of help with templating (and rules, and design conventions, etc.).

Does this site get a lot of use from noobs like me? Or is it mainly used by people who have already developed some Magic design know-how?

At any rate, the templating reads awkwardly. That's probably a sign this mechanic isn't worth pursuing. I'll try it out in this set though (but not at common).

Sorry, looks like I missed this reply until now... There's a great variety in Multiverse's users. There are some of us who're very practiced and skilled in modern templating and design conventions; some who generally know the modern terminology but don't make too much fuss over it; and some who tend to write cards phrased the way they were in Alpha, like this kind of thing :)

My general approach is to offer templating advice whenever asked for it, and to point out when an ability would have real problems working within the current rules, but otherwise to avoid nitpicking templating and terminology unless it's by somebody who I know will appreciate it.

I think I might appreciate some of that templating-and-terminology-nitpicking myself. A good chunk of the fun I derive from making these cards comes from trying to speak in Magic's peculiar language. So I'd be happy to have you and others school me in Magic-ese.
