hmm reading your fnm update if other counterspell decks are an issue, Dovin's Veto or Dispel are both pretty decent at protecting yourself. Though I guess I suggested that back in comment 7.

Hmm with you running 6 spells that combo with it I almost wanna suggest a single Knowledge Pool , when you have an opponent cursed or lil teferi down the opponent essentially can no longer resolve spells from their hand.

Demarge, Dovin's Veto is extremely good, and I am now running one copy. I will try Dispell as a side card. I think Knowledge Pool is a pretty good card for my deck, but I am trying not to buy any cards for a while (Throne of Eldraine Prerelease). By the way, thanks so much for all your help, it has been extremely useful.

np it is always entertaining to try to tune suggestions around certain limits. Now prerelease time is a very good time to go trade hunting.

Just realized that Knowledge Pool is really bad with Approach. The second one has to be cast from your hand.
