There are probably better lists but I like the simplicity of this one and the 666-card deck.

If you are playing Limited (i.e. Draft or Sealed decks) then you can have as many copies as you have in your card pool.
Although you may have some trouble finding 200 cards to use in a Limited event :)
20x Black Lotus
20x Channel
20x Fireball
As long as you get 2x Lotus, 1x other two in your opening 7 cards, first turn kill. Play two lotus, sacrifice one for green, one for red. Play channel with green. Give up 19 life. Do 22 damage with Fireball.
Black Lotus is worth five figures these days, so building that deck would be very expensive. Replacing them with Mountains and Forests gives you a deck for less than ten dollars that can routinely kill on the fourthish turn every time, though.
The second one is even sillier: (see edits and citations below, I slightly mis-remembered this one, but the concept is the same)
60x Shahrazad
This was Richard Garfield's favorite card. But due to the way the rules work, a subgame within a subgame within a subgame within.... means that you win, due to the way that rounding works.
31 Ancestral Recall
25 Black Lotus
3 Timetwister
1 Braingeyser
If anything gets countered, you are very, very likely to be able to keep going and win the same turn.
Timetwister lets you recycle, so you can generate infinite mana.
Braingeyser kills the opponent, and doubles as card draw itself, in the unlikely event that you stall out.
You also don't lose to a turn 1 Lightning Bolt, like you do with Channel.
A mulligan to two still has a fairly high likelihood of winning on the first turn.

715.3. Because each player draws seven cards when a game begins,
any player with fewer than seven cards in his or her deck will
lose the subgame when state-based actions are checked during the
upkeep step of the first turn, regardless of any mulligans that
player takes. (See rule 704, “State-Based Actions.”)
Mox Pearl is simpler and faster than Plains!
EDIT: Looks like Mox Pearl is the right way to go.
