Here's a WUR Delver deck I'm currently using in Pauper on MTGO. in the future I plan on either adding some more white cards or toning back the white mana, but for now the deck is playable. Hopefully the sideboarding guide will prove usefull, although I think that most players understand Delver by now.
Kor Sanctifiers : Sideboard these in whenever you see enchantments as a threat, for example, when your delvers keep getting shut down by Journey to Nowhere . You can replace both of your Gideon's Lawkeeper s, as well as any combination of vapour snag]s] or [journey to nowheres, depending on your opponents other threats.
Kor Hookmaster : Swap in your Hookmasters in the place of three AEther Adept s and a vapour snag so that you can shut down your opponents creatures without having to return them to your opponents hand. This is useful when it is beneficial for your opponent to play the card multiple times, such as an [aether adept of their own.
Counterspell : This swaps in with your Mana Leak s. It is useful when you need to counter spells in the late game and your opponent has 3 extra mana open. It is also important to note that counterspell often cant be used early in the game with this deck, as it has 3 colours, and 4 Karoo lands.
Fireblast : If youre up against an opponent who is light on creature spells you can use this in the place of your Lawkeepers or Adepts to get in some more damage, which may be critical in some matchups. It can also boost your instant and sorcery to other card ratio to help flip your delvers.
Please fell to leave comments and suggestions!
You have WAAAY to many lands for such a low curve. You top out at 3 and you're running 26 lands which is common for control decks that curve out at 6 drops. And you run 4x Ponders that will help you hitting crucial land drops. I would consider going down to somewhere around 20-21 lands instead and then adding a few more if you notice you get screwed often.
Thanks for the feedback fauhncy! I'm currently playtesting the deck with a focus on finding the right manabase. I'll be updating the list when I've found something that runs consistently.
