The idea is to Journey to Nowhere or Oblivion Ring a Mogg Fanatic or Sparkmage Apprentice . Then cast Worldfire and drink the tears of people who once called you friends.

Mentor of the Meek helps you draw into what you need. Seething Song and Mana Seism are your ramp cards. Holy Day and Kami of False Hope help you kill time.

Lobber Crew is in the sideboard for multiplayer.

This deck really needs a mulligan if you don't have at least three of the four parts of the combo in your hand (1-2 ramp cards, a Worldfire, a damaging creature to exile, and an exile card). You should also mulligan if you get two Worldfires, because who cares about the second one?

This deck is very consistent, but very slow. It usually wins at around turn 7, and without a counterspell it is almost impossible to negate the win. Getting to the point of casting Worldfire is the difficult part.
