An all-in Triskaidekaphobia deck for Standard. Please give me suggestions.

Get the opponent to 13 via the drain cards or the Tree of Perdition. Everything else is focused on removal, aside from 4 Dark Petition (to get the Tree or Triskaidekaphobia). If I cannot win with Trisk, I have more drain in SB to try and kill them the old fashioned way (getting them to 0)!

I do realize that there's a danger of losing myself to Triskaidekaphobia, but that's part of the fun! ;) Also, there's several cards in the deck that I could use to adjust my own life total, like Damnable Pact, Cryptolith Fragment , Collective Brutality, and Alms of the Vein .

Just recently added the Succumb to Temptation and Caves of Koilos so I can adjust my own life total at instant speed.
