Losing to Krark's flip on your Flusterstorm seems like one of the better things you could do, I think I would start there. Also its worth mentioning that Ravenous Trap is unaffected assuming it's condition is met. Seems to me his largest downfalls are that you almost certainly won't be running the up-to-12 various Forces that are available and that he is miserable with a Sphere around, but those can be mitigated in deckbuilding. I'm assuming that anyone playing this card is accepting the addition of greater variance to a high-variance game and ignoring that argument.
Helping your opponent stock their graveyard is always a rather dubious strategy in Vintage, but wow, mill 26 for 0 is certainly efficient enough to deserve respect.
I am also a fan of this archive trap plan.
