1.
The absolute best card ever printed for Magic: The Gathering.

This card is so good that people today buy it for prices of AT LEAST $1000.00

This card is so good that cards that were specifically made to do exactly 1/3 of what it does (Lotus Petal) and cards that were specifically made to be insanely crappy versions of it (Lion's Eye Diamond) got banned along with it because they were abused just as much.
If you have a Black Lotus, DO NOT SELL IT!!! Wait a few decades (make sure to keep it in mint condition) and then sell it when its average Ebay price is about $5000.00+

Codename of a legendary female of the Chinese Mafia in the Philippines, rumoured to be the real leader secretly controlling the organisation behind more prominent figureheads. She is also alleged to be a math wizard and controls all organisation finances and investments (both legal and illegal). Up to this day, her true identity is still unknown, and is kept that way due in large part to her significance to local mafia operations.
Cunning tactical move or urban legend? Even until now, the Philippine NBI (National Bureau of Investigation) has yet to confirm the existence, and much less the identity, of the mythical Black Lotus.

A rare card in the Magic: The Gathering series. Printed in series: Alpha, Beta, Unlimited.

People who buy Black Lotuses are nerds and stupid (they cost >$500 each)
Person1: I have a Black Lotus.
Person2: Wow, you're a retard.
