Origins Toolkit White Black Deck

I am using the same white cards I have in the White/Blue deck (all of them!). I added the black ones.

Here I use Strive to buff up my creatures.

Here I cause an opponent to sacrifice an attacking creature.

Here I hit past red creatures.

Use of white enchantment.

Use of target removal.

More use of target removal.

Nightmare is good for mono-black, but not good with just the cards in the toolkit, which does not have enough black cards for a mono-black deck. In this deck, I got to cast it as a 3/3 for 6 mana: not good!
