V. Charm gets Nought into play or it protects him from Decay if your up against BGx. Against anything not playing Decay, Trickbind is strictly better. The thing is though, the BGx decks are usually the toughest matchups, and they're increasing in popularity. It's really a meta call I think but I'm not the biggest fan of Torpor Orb, and would never play it unless Goblins was taking over your meta.

Divert is cool and all, but it just isn't flexible enough imo and there will be matchups where it's completely dead. Having a handful of dead cards is really frustrating, and we already have cards that lose a ton of value on their own(Dread) or in the lategame(Daze, sometimes Stifle). Brainstorm can't fix everything, and I prefer the card that is a little more flexible than Divert. I do think that Divert is probably better against BGx decks, so the decision really warrants ample play testing and metagame prediction.
