This was my overall impression of how the card would play out, and I excluded it based on the fact that most of these aren't available to the white decks in my cube. Sweepers are, of course, but not Counterspells (as
doesn't exist), no card manipulation (as both
and
don't exist), no SDT, and no tutors. I guess things like redundant lifegain,
Wall of Omens-style cards, and maybe
Phyrexian Arena or somesuch can get there, but I think it will have a harder time doing something useful in my cube than in yours. Who knows though, I might still find a slot for it in the future, you are right after all that you won't know if you don't try
