Your 5-0 streak with that deck didn’t go unnoticed 😉 – really a fun deck and I am about to switch my mono-u delver to your list, because it looks much more like what I love to play, with the additional reach of red in the deck.
Can I ask you to provide sideboarding for Bogles (because Kuldotha Boros and Bogles are the two decks I have to fight most of the time, as that is what my colleague plays)? Or would you change the sideboard slightly if you would have to fight Bogles more often (adding Curfew or Aura Flux maybe?)?
Oh, and I guess the lands are again snow lands, since you still run Skred – the list you link shows them as standard lands.
