Ant's Big Spell Priest

This is the priest deck Ant took to Amsterdam to compete for the World Championship. This deck was banned by his opponents in both of his matchups. Though we never got to see it played in action, I thought it was genius already to bring Spiteful Priest instead of Highlander, so I threw the deck together and started playing it.

After a couple weeks of playing off and on, I still really love this deck. To no surprise, never running out of tempo options can win you a lot of games. The addition of the Prince Keleseth & Patches the Pirate packages are so deadly you almost forget the entire point of the deck is to play Spiteful Summoner. And by that time, you usually net a concede from the opponent who has no way to deal with a turn 6 Tyrantus.

While this video is not Ant's exact list, you get as general idea of how the Keleseth/Patches packages boost the performance of this archetype.
