MTG Salvation

Hi, I've been playing Martyr proc for about half a year now (in paper), and currently I'm playing a version of Lear_the_cat's Bant Glittering Proc deck. I've been doing pretty well at FNM/Win a Box, beating aggro, humans, affinity, burn, death's shadow, and other high meta decks, but I'm still having trouble with a few decks. Every week, I'm maybe 3-0 or 2-0 and placing pretty high, but then I run into a couple of guys with the Krark-Clan Ironworks deck, and it just seems unbeatable. I'm thinking of Sundering Growth that I can grab with Glittering Wish and taking out two Ghostly Prison(s) for Stony Silence(s). I'm also having a little trouble with Storm (as many of you are, I think), and 8-rack. Any suggestions, for cards or plays, would be greatly appreciated.
