have you tested this?

I don't need to be a tool and explain all the math like mrharmful (way to live up to your name, btw - and mr knight, i will say that it is one event, not conditional, as you're drawing all 7 - BOOM! - at once), but here's the number.

0.000000559%

That's the chance of getting this on your opening hand. I hate mill-decks, and you know it, but at least I can still laugh when I get milled, and laugh more if you ever try this deck (for the sole purpose of the one-turn win, at least) against me. ;)

But even still, I'll laugh.
