deal w/ prosh+purphoros

[particle]

playing mono black with {geth, lord of the vault}.
having trouble dealing with the combo of damage from {prosh, skyraider of kher}, {purphorous, god of the forge}, and {doubling season} etc.  I have things like {steel hellkite} to "destroy" but nothing to deal with {purphoros, god of the forge}. and he is also normally not a creature. any ideas for good edh colorless or black exile options?

I mean  {Ashes to Ashes} for when he is a creature.  {Torpor Orb} stops te damage at least. Hope this helps

{Blood artist} + {Illness in the Ranks} +{Falkenrath Noble} + {Exquisite Blood}

Mono black isn't very good at dealing with enchantments, it's just not part of Black's color scheme. {All is Dust} probably really is your best bet, and black tutors to get it out of your deck.
