esterday, I wrote about Yuuya Watanabe and Jund in the 2012 Magic Players Championship. I indicated that wasn't the last we'd see of either the player or the deck, and, in fact, at the very next Pro Tour, we almost witnessed a repeat performance by the same player and deck. Ultimately, though, he was defeated in the finals by Stanislav Cifka playing a Second Sunrise–based combo deck with a hotly contested name.
The deck is an evolution of a much older deck called Eggs that uses a cycle of artifacts called "eggs" (since they have names like Skycloud Egg). The eggs are artifacts that cost one mana to play and can be sacrificed to turn two colorless mana into two colored mana of a specific combination and then draw a card. This has led to any cheap artifact that can be "broken" to draw a card occasionally being called an "egg."
The Egg Combo deck (also called Second Sunrise Combo or Second Breakfast) builds up a board full of "eggs" like Chromatic Sphere, Chromatic Star, and Conjurer's Bauble before beginning a big turn in which the player sacrifices all of them, and anything else in play, to draw more cards and generate whatever effects happen to be available before playing a Second Sunrise... which returns them all to play, letting the player sacrifice them all again. Lotus Bloom can be sacrificed for three mana, which is enough to cast Second Sunrise, and the eggs draw you to more copies of Second Sunrise or its sister, Faith's Reward. After reiterating this loop several times, the opponent will usually fall asleep, at which point the Second Sunrise player can declare him- or herself the victor. (Failing that, it's possible to actually deal lethal damage by reusing Pyrite Spellbomb.)
