I'm just wondering if anyone knows if i can build an at least decent mono black deck out of the kind of small collection of cards that I have right now.

Here's a link to my collection list and the .csv file updated as of today.

Hi.

I don't so how you could build a decent deck with those cards. Only if you have a friend to play with, that has the same level of cards.
