All is Dust

Excellent choice for removing tricky permanents in colors that don't normally have access to those answers. As someone who plays primarily EDH, this card works wonders in my mono-green and mono-black decks, giving them outs to a lot more situations.

I use this card with my deck built off of Slivers and Eldrazi, I use ghostflame to make all slivers colorless, then hivestone to make all my creatures slivers (I know most eldrazi are in fact colorless, but with this they get haste from my horned sliver, shroud from crystalline, lifelink from essence, and cannot be countered from root) I have It That Betrays out, so everything that is sacrificed after this card is played, becomes mine, and all their creatures become slivers. Played an 8 player game in my fraternity, no one wants to play my deck anymore. Cannot recommend this card enough.

how about ghostflame sliver and all is dust lol

Hmmm, It That Betrays plus this card = Win button.

This is just crazy even better thn wog with the eldarzi lands that can make this even cheaper than wog. and say they have indestructible doesnt matter they sac it anyways lol

This is nuts... With the eldrazi lands, this can easily be cheaper than WoG, and with an eldrazi deck... hmm... only your opponent suffers? What? This is sick... Sicker than baneslayer... Just sick...

Awesome combo-
Painters servant+All is dust+GET MORE LAND+Soulquake+Megrim+Chandra Ablaze's second ability+Blood Tribute+Sanguine Blood. KAWHAMMO! Just use in a Grixis colored scarecrow deck with a few Nicol Bolas'. Belive me, it works extremely nicely. Another combo involving Chandra Ablaze's second ability would be Soulquake+Platinum Angel+Megrim+Chandra Ablaze's second ability+Death's Shadow.

Seeing as All is Dust doesn't destroy colorless permanents, and with a new Artifact block lurking just around the corner, I really expect this card to rise in popularity once more. All is Dust has to be one of the best spells available to an Artifact control player - a one-sided board sweeper that, on top of leaving all of your permanents intact (well, with the exception of Tezzeret), only requires colorless mana!
The manacost may be a bit high, but running a couple of Eldrazi Temples in your deck should solve that problem (remember: they also tap for colorless mana to use on your regular artifacts!), and All is Dust is usually a late-game spell anyway.
