I could never figure out what the appropriate situation is for wishing for Returns. All it seems to do is to inflate the storm count some more (and a lot of the times that is overkill, on top of that sometimes you run into an all-mana hand leaving you stuck), or if you know your opponent has ETW hate and need to dig out the Belcher (but then again you can just wish for tutor...)

I tried wishing for it sometimes in testing, but results weren't really awe-inspiring. In real games I've never wished for it.
