title: Power Nine
context: The "Black Lotus" card can be played at zero cost, and grants three mana (the game's primary resource) when sacrificed (discarded from play). Thus, the card gives the player an enormous jump in the early stages of a Magic game. Former Pro player and Magic writer Zvi Mowshowitz has declared Black Lotus as the best card of its type of all time, claiming every deck in the history of the game is better with a Black Lotus in it.[7] It has since been banned from all official tournament formats save for Vintage, but even there, it is limited to one copy per deck, compared to the normal allowance of four.[8] The illustration on Black Lotus was painted by Christopher Rush, who was at the time a Wizards of the Coast employee. The Black Lotus illustration is a depiction of a black lotus flower over a foliage backdrop.
