So I have been kicking a round a U/R Delver list in modern that seems pretty solid. mostly it looks to stick a Delver/Lavamancer early then just dominate the board or finish off their life with burn. I am thinking about having the sideboard be one of a few things; either a traditional sideboard with normal hate cards or a trans-formative sideboard into RDW, Pyromancer Ascension, or Splinter Twin.

I'm thinking PA because I'd board out my creatures, blanking any kill spells. However I have the cards to do Twin, and RDW because Iove the Shrine of Burning Rage.

I'd appreciate any feedback because I'm planning on GP Chicago since I just moved to town.
