Here’s what I decided:

I like idols, more or less, but I don’t want them to completely control the game, either. So here’s the deal: if there are fewer idols than three left by the time we get to the merge, I’ll add enough to get to three shortly after the merge (I won’t announce whether I had to add any or not). If I add any more, it will be within two post-merge challenges, and I’ll never add any more.

The next challenge will be posted at something like 2 in the morning here, so you can get at it tomorrow morning.
