Ooh, maybe the best part of spoilers is here: The commons! Is there anything super crazy for Pauper?
-Blazing Volley seems like a very, VERY viable alternative to Electrickery. It's probably ultimately not quite as good since instant speed on Electrickery can net you card advantage pretty easily, but one mana is very relevant to snipe a Delver before it can try to flip when you're on the draw.
-Wander In Death is a much better version of Death's Duet, which is admittedly a bit of a fringe card already, but it's one I play and like. I'll definitely be slotting this in over Death's Duet in my deck.
-Trespasser's Curse seems like it has sideboard potential. It comes down early, completely shuts down infinite combos based on creatures, which is most of them in the format (including my Ivy Lane Denizen/Safehold Elite shenanigans), and seems seriously backbreaking against stuff like goblins and Kuldotha Rebirth in an aggressive matchup. Which admittedly is a bit narrow, and it arguably comes down a turn too late to catch a lot of explosive plays, but if it works it seems hard to recover from. Just not sure it's ever going to be better than more removal boarded in instead.
-Grasping Dunes might be something since there are a lot of high-priority one-toughness creatures that it can kill, although it's risky against Delver since it may flip before you can snipe it.
