I thought this deck could be functional in some kind of environment where you make sure the eggs are somehow desirable to numerous decks. Maybe the mana is clunky or something. I'm not sure. It turns out there's only ten "eggs", so it doesn't look too likely without singleton break.On a sidenote, does somebody have a functioning "Eggs" archetype in their Cube? I would love to be able to play that deck again!
There's probably something to be done between Brought Back, Second Sunrise, Cosmic Intervention, and Faith's Reward as mass permanent retrieval as well as quite a few cards that target only one card, often creatures, that died during the turn. Some sort of white sac deck, maybe GW Revolt, possibly with an artifact theme to make the eggs more relevant. If someone wanted to pull it off, I'm sure they could, but it's not going to be the monster that Cifka had.
