Excavateur soldevi  

Browse allows you to look at the top five cards of your library and choose one and put it in your hand. The other four are removed from the game. Soldevi Digger allows you put a card from your graveyard on the bottom of your library. Together, these cards create a powerful engine that can put your opponent into a soft lock.

Browse can quickly reduce your library to no cards. The Digger then allows you to put the top card of your graveyard onto the bottom of your library, eventually making your library a small stack of just the cards you want. It's important to remember that Browse says "look at the top five cards and choose one." If you have only one card in your library, then you just put that card into your hand when you activate Browse; since there is no actual "card draw" involved, you don't lose the game. There have been decks that relied on this combination and a single Lightning Bolt for the win. With this deck, you simply Dig and draw your Counterspells to protect your win condition. If necessary, you can Dig up a Disenchant or a Wrath of God. It's almost impossible to conceive of a player losing from that position.
