I appreciate you taking another look at the differences in the suggested solutions. I don’t agree that there’s anything “dangerous” about using Reposition. But I do hear the overall point – you’d prefer to have a random-deck gather.
If someone is interested in implementing that, it will help that we’ve fleshed out the issues, here and in other threads. [And I think your list of links will be a useful reference too
– even if a few of them are outdated v1/v2 issues.]
