jace, the mindsculpter... 3 counters 1, look at the top card of an opponents library, you may choose to put it on the bottom -2, return target non-land permant to the top of its owner's library 0, draw 3 cards, put 2 cards from your hand onto the top of your library in any order -12, exile(remove from the game) target player's deck, then that player shuffles his/her hand into their deck. so basically u start lookin at their deck and bouncing stuff to the top, then when your done you go t(^.^t) and remove their deck from the game and make their hand their deck. after that, since your probably playing mill with jace, you just mill the rest of their library and pass turn. then they look down, see no cards in their deck, and go .....-table flip-
A king decided to let a prisoner try to escape the prison with his life. The king placed 2 marbles in a jar that was glued to a table. One of the marbles was supposed to be black, and one was supposed to be blue. If the prisoner could pick the blue marble, he would escape the prison with his life. If he picked the black marble, he would be executed. However, the king was very mean, and he wickedly placed 2 black marbles in the jars and no blue marbles. The prisoner witnessed the king only putting 2 black marbles in the jars. If the jar was not see-through and the jar was glued to the table and that the prisoner was mute so he could not say anything, how did he escape with his life?
He picked a marble and swallowed it and showed everyone the other marble which was black, making it seem as if he picked the blue (one he ate) and he was freeeee
