I was actually thinking of writing a post in thread discussing the possibility of doubling down on LD with Sinkhole as a means to address the rise of combo. I'm glad that Richard Cheese went out and tried LD in practice. I had an idea that one way normal Jund could differentiate itself as a distinct variant of Jund that isn't just a weaker version of Punishing Jund is one that tries to emulate Pox post-board, with Sinkholes main/SB and Extirpates to rip apart combo/control decks. Since normal Jund lacks Punishing Fire and are thus more able to produce black mana, it might be a wise direction to really up the count on black spells in the deck to combat combo and control.
