While Long.dec above is a pretty perfect example of the kind of Draw-seven deck that has historically been the most common source of turn 1 kills the format was once known for, the most extreme example since the advent of the four-of rule is without question the following Broken LED deck from the 1999 Duelist Team Challenge at Origins

It may be green, but the powerful Phyrexian mana mechanic means that any deck can wield it at the cost of just 2 life
