A German pro player, Arne is a great mind for MTG and also a great teacher of the game–which shines through in his quality writing. He's also one of the best players currently active on the pro scene–as evidenced by his recent top 8 finish in Pro Tour Outlaws of Thunder Junction. He's known as a constructed expert, and there's no one to sooner trust about control and midrange decks in newer formats like Standard.
