With the ability to run this small number of Uncommons, the format is certainly defined by the Uncommons that are played, and in this particular case, the Uncommons that were considered Commons due to their printing as a Common in an earlier set. Like I mentioned last time, I made the choice to build around the Uncommon powerhouse Corrupt. Here is the deck that I ran in this event:
While I initially thought I had a pretty strong build, I was somewhat disappointed with my results. I ended up going 2-2, losing both Round 3 of Swiss and Top 8. I faced two very aggressive decks in Round 1 and 2, surviving thanks to the ample Lifegain available to this deck. Then in Round 3 I was demolished by a Hexproof deck that I really had no answers to. Then, in Top 8, I drew poorly and really never got going against a fast Selesnya deck.
If I ran this deck again, I would probably cut the Sengir Vampires for more removal and included four copies of Shrivel in the Sideboard. Shrivel would have been absolutely back-breaking against all three of the decks I faced in the Swiss rounds, and its absence was clearly a mistake on my part. It is also worth looking at the other Mono-Black deck ran by Malum for some other ideas worth trying out.
In any case, for your viewing please, I have included a videocast of my Round 1 match. I hope you enjoy watching it, and I will see you next time!
