A cube where players draft 12 cards to build 7-card "decks." Players start at 1 life, and can't lose for drawing from an empty library. You will always start the game with your whole deck in your hand, basically, but you can also take mulligans to selectively put cards back into your library.

There are a number of different strategies here, most of which are outlined below:

Laboratory Maniac
Lab Man is a potential wincon for Mana Crypt or other ramp decks, where you can try for a win in your draw step, or try to win by making yourself draw a card. Currently there's a high likelihood that I remove this for being worse than other wincons. Can also speed up the win with Mishra's Bauble.

Narcomoeba and Creeping Chill
These cards take advantage of mulligan rules. You mulligan to put these cards back on top of your library, then mill them in some way. The two ways to do this here are Thought Scour and Stitcher's Supplier.

Disciple of the Vault
The plan here is very simple: Resolve a Disciple, then put an artifact into your graveyard from the battlefield. Mishra's Bauble, Lotus Petal, or Hangarback Walker all win with this, as well as some other similar cards. Warlock Class is an alternate version of this deck.

Keen Duelist
If you can turbo this out turn 1 and put a card on top with your mulligan, you can potentially slam your opponent for a bunch of damage.

Fell Stinger
This little Scorpion can sting your opponent off of a Dark Ritual or Mana Crypt.

...

Leyline of Lightning
This is one of the most potent cards in the cube. The spirit guides and Gemstone Caverns can be useful here, since they let win off of your free interaction in response to your opponent's move if you're on the draw.
