"Searching" your library face-down

[TylerEss]

This is as much a tournament etiquette question as anything else. When searching your library, do you have to actually look at the card faces?

It is my second turn's upkeep. I have in play a Mox Sapphire and Island. In hand I have Brainstorm, Ancient Tomb, and Darksteel Colossus. I pour out my wine to Pallas Athene and topdeck Tinker. Can I Brainstorm, put the fat back as the top card of my library, Tinker my Mox away, and simply flip the top card of my library into play and then shuffle?

This is showing off, yes, but is it illegal?

I don't really see a problem with it, as long as you get the appropriate card.

And as long as you actually do shuffle. --Matt
