ThatGuy's Ploy of Insanity

(Start the game with this conspiracy face up in the command zone.)
At the start of the game, starting with you, each player chooses a nonland card in their library, reveals it, then shuffles their library. All cards chosen this way and cards with the same name as the chosen cards have their rules text replaced with "At the beginning of your upkeep, cast this card without paying its mana cost" and "Put the top 50 cards of your library into your graveyard."
