Spiteful Visions kills you first

This deck takes the "he draws first" problem of howling mine and turns it into a plus!!

I made this deck a little while ago... it looks solid on paper, but in practice it makes me make some dumb plays. I'm trying to iron out the kinks. I play 2HG mostly, but i'l like to have a SB for other multiplayer formats or even duels
