Let's be calm, guys. We're just debating stuff on the Internet here.

It's certainly true that you can't predict DM behavior without knowing the DM in question. It does us no good to predict how someone's DM will rule something. That's probably why official rulings are so popular online, because at least they're something.

As far as whether rulings that contradict official rules are still valid, or whether we should consider them house rules and not rulings, I made a separate thread for that. It doesn't really pertain to deck of many things.
