The latest Mythic Championships just concluded hours ago with the Jund Sacrifice getting the trophy and title of Champion. The deck was played by Pro Player Poitr Glogowkski (@kanister_mtg on Twitter). He just could not be stopped in during the Top 8 matches wherein he placed 2nd prior, though those were three-game matches in the upper bracket.

He defeated World Champions Seth Manfield, PV, and Javier Dominguez before finally defeating the lower bracket finalist Brad Nelson who played Simic Flash. The finals match was somewhat epic as the counterspells and card tricks of the Simic seemed to be more dominating than that of sacrificing and creature-recursion.

Here below is his winning decklist.
