Why the arbitrary no-discard clause? Seems like this will either be broken on the merit of other cards or not at all anyway, and it feels too rigid and confining.
Well, then you'd play it with Intuition and Bazaar and it would be insane. I mean, UUU for 6 cards is ridiculous, especially when it can be divided up among phases/turns.
I figured I'd keep it to Quiet Speculation...1UUUU for 6 cards is pretty sick. If you all agree it is not broken with discard, then I could take out the clause.
