Round 1: Stiflenaught (2-1)
This guy's deck is sweet - it's the classic dreadnaught -> stifle plan, but lazav also works to become dreadnaught.
G1: I fall behind early and let a dreadnaught resolve with no plow. I end up dying in pretty short order.
-SB: +2 Disenchant, +1 Path, +1 Narset, +2 CJ | -2 Stoneforge, -1 Jitte, -1 Pierce, -2 Daze
G2: I land a delver, but it takes a while to flip. I answer bob with a plow, and then daze something (I think a LtLH). He kills my delver after a while, but at some point I resolve a TNN and a stoneforge to batterskull that get there. At some point this game I remember disenchanting a lazav, which was very fun.
G3: I also land a delver, but he ends up with a strix to stall it. After piercing a few threats, I sculpt the hand of 2x plow, 2x disenchant. I plow the strix over disenchant since i really don't want to plow a dreadnaught and give him 12 life. Sadly, he has push for my delver, i plow the bob he plays, and we look at each other for a while while drawing blanks (he plays a needle on JTMS at some point). He plays dreadnaught and stifles, which I immediately disenchant. On the next turn, the exact same thing happens and we both play hellbent. Eventually, I draw a stoneforge, which ends up getting the batterskull to go all the way.
