What's the 'strongest' Magic card?
Power Nine
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.
Lord Voldemort
In "Harry Potter and the Deathly Hallows", Voldemort furthers his quest for ultimate power. He disposes of the Minister for Magic and replaces him with Pius Thicknesse, who is under the Imperius Curse. Establishing a totalitarian police state, he has Muggle-borns persecuted and arrested for "stealing magic" from the "pure blood" wizards. After failing to kill Harry with Draco's father Lucius Malfoy's borrowed wand (to avoid the effect of Priori Incantatem), he goes on a murderous search for the Elder Wand, the most powerful wand ever created, seeing it as the weapon he needs to overcome Harry's wand and make him truly invincible. He goes on a quest that takes him out of the country to Gregorovitch's wand shop, where he kills the old wandmaker. His journey also takes him to Nurmengard, the prison where Gellert Grindelwald is kept, and he kills Grindelwald as well. He finally locates the Elder Wand and steals it from Dumbledore's tomb.
