Zur's Weirding in Landstill/4cC

Could Zur's Werding find a place in Landstill or 4cC? Certainly not as a maindeck card, but as a SB solution against some decks.

I think it's pretty good against combo, effectively negating the key card he needs to go off for almost no cost, since life is probably a non-factor against combo.

In Landstill, after establishing a small board advantage, just using Zur's Weirding to avoid your opponent from getting solutions. Even if he can do the same to you, you have lots of draw cards - Standstill, Brainstorm - for him to stop all of them. He cannot afford to let you draw the Bstorms or Standstills, since you'll be having access to too many cards he'll need to stop. I think you can play the Weirding to your advantage.

In 4cc, coupled with Exalted Angel it is almost game over, as you are effectively negating him his draw phase for no cost at all. This would make a "quick" Angel much more dangerous.

And it doesn't fire madness effects. Is the Weirding just too slow? Are there any other decks that can use it? I need to playtest this.
