I ALWAYS board it versus any deck with blue, and also versus elves. I did board it on recently versus Junk when I saw him playing Sylvan on G1, and luckily it paid off as he turn 2 Sylvan Library'd and I turn two played Chains. ha! (no I dont think it's the correct boarding in this case but it was fun seeing happening).

Vs Blue decks it's almost like negating at least 8 cards, realistically speaking 7. And is beast vs combo. It works best versus opponents who kept hands because of BS.
