its a stone cold killer. it can block at 5 and in an artifact deck its' first effect can quite easily make it a 12/5 or better

Deathtouch seems a bit redundant.

Why on Dominia's sake is this only getting a 3.2? Very high defense, makes it outlive most burn spells, black prevents a lot of removal, who cares how high much damage it causes as 1 damage kills. Not only that but it kills through regeneration. The only negatives I see is maybe, a bit pricey, and it doesn't cause a lot of damage outside of an artifact deck to a player, but then just keep it in an artifact deck. So, just the price. 4.5/5

I wonder if this card can kill creatures with Pro-black, because it says, "Whenever Mephitic Ooze deals combat damage to a creature," pro-black only prevent damage from black sources, it doesn't prevent them from DEALING it in the first place. Any guru help here?

702.15e. Any damage that would be dealt by sources that have the stated quality to a permanent or player with protection is prevented.

Since Mephitic Ooze is a black source it cannot deal damage to a permanent or player with Protection from Black.
