Eggs is a powerful and consistent combo deck that wins the game on turn three or four by looping Second Sunrise and cheap artifacts that tap to draw cards. (I'll explain exactly how it works below.) It's extremely budget given the Modern-format baseline, but it's easily disrupted by graveyard hate and Chalice of the Void. This deck is a favorite amongst math nerds like myself, as the fractions of a percentage one can acquire by playing the cards in the correct order will add up fast.
Chalice of the Void is legal in Modern, but we have no idea how popular it will be. Eggs is very well positioned as long as that's the case.
This deck's ability to be competitive is heavily dependent on the metagame. If players are afraid of Living End and bring in cards like Tormod's Crypt and Relic of Progenitus, then this deck might have a lot of trouble. However, if players decide that Surgical Extraction is the best graveyard hate spell because of its strength against combo, then this deck will be absolutely fine.
Surgical Extraction may seem like a nightmare, but New Phyrexia introduced a powerful spell that fits perfectly in the strategy and doubles as an incredible defense against Surgical Extraction. Noxious Revival is a strict upgrade from Reclaim that can grab the targeted card from our graveyard and put it on top of our deck even when we don't have any mana left in our pool.
Here's how it works. I spend the first two or three turns casting artifacts that I can sacrifice to draw cards. I sacrifice all my artifacts once I find a Reshape (to tutor up a Lotus Bloom) or my Lotus Bloom comes off suspend. In doing so I draw a bunch of cards. Then I use whatever Ponders and Preordains I have to find a Second Sunrise. I use Ghost Quarter to target my own lands and search up additional islands to empty my hand of as many artifacts as possible and thin my library. I cycle Edge of Autumn and draw additional cards.
When I'm out of mana or cards, I sacrifice my Lotus Bloom for white mana and cast Second Sunrise. In doing so, I generate a huge amount of mana by bringing back all the lands that I destroyed or sacrificed along with the Lotus Bloom. All the artifacts are also returned to the battlefield, and I'm able to sacrifice them all again to draw a lot of cards. If I'm unable to find another Second Sunrise, then I use Noxious Revival to put the first one back on top of my deck and then draw it by sacrificing one of my artifacts. I cast all the artifacts I draw and use Ghost Quarter on my own lands after I tap them for mana again. I use this mana to cast more artifacts from my hand and use them to draw more cards. When I run out of mana or cards I sacrifice my Lotus Bloom and cast Second Sunrise again.
Eventually, I draw my entire library. I'm then able to use Conjurer's Bauble to loop the Second Sunrise and use Pyrite Spellbomb to deal 20 points of damage to my opponent. If my opponent has some type of Ivory Mask or Leyline effect in play then I can use Sunbeam Spellbomb to gain infinite life and loop my Noxious Revivals to ensure I never run out of cards and will eventually deck my opponent.
