The Reveillark Combo Explained

The popularity of the combo deck called Project R (Project Reveillark) makes us wonder how the combo is performed. After reading an article in the official MTG site, I was able to find the explanation of how it is done. Here it is, as quoted (I think that's the best explanation and I got no time to rephrase it. Lol.):

"Imagine that using your copious Careful Considerations and Mulldrifters, you have got Reveillark in the graveyard and a Body Double in hand along with Mirror Entity. Provided you have something productive in your graveyard (a Riftwing Cloudskate, say, or simply an evoked Mulldrifter) you can "go off" with this deck. The next step is to activate Mirror Entity for zero as many times as you'd like, all in response to one another. When you finally let the first Mirror Entity roll, what happens is that everyone dies, including the Reveillark and the Mirror Entity. When the 'Lark bites it, return the Body Double copying Reveillark (and something productive) and let the next Mirror Entity activation resolve. Now reverse it and pick up the original, and so on interchanging the two 'Larks, then repeat until you've returned all of the opponent's cards, drawn your deck, whatever you like based on the cards available to you... provided it can be accomplished via repeated access to two 2-power creatures. Your advantage on the board at the end of it all should be massive one way or another, plus the deck will often be in a position to win with a single attack powered by Mirror Entity."
