The situation (at an FNM) is as follows: Player A resolves a Dig Through Time, picks his two cards, puts the rest on the bottom of the library and puts his library back where he wanted it to be.
Player B picks up the top half of Player A's library, sets it aside and puts the bottom half on top of it. A second later, player B realizes his mistake and calls a judge.

How do you rule this? How would the ruling be different between REL Regular and Competitive?

I recommend to read this thread where this scenario has been discussed (under compeititve REL), including a (i guess you can say ‘O’ answer from our dear Uncle) how to fix the situation. I think ist reasonable to say that a lot of what have been said could be used at Regular REL as well. Without the penalties of course.

Thank you very much, I hadn't thought to search in the Competitive Board. That thread was very helpful!
