Lifegain wins through incremental value engines like Case of the Uneaten Feast, Lunar Convocation, and Moseo's Infusion recursion rather than raw tempo, so Duress can proactively strip these engine pieces before they take over. Strategic Betrayal is very strong since it removes a key threat while also exiling their graveyard, cutting off Moseo's recursion and any Case of the Uneaten Feast graveyard recasts. We Say Thee Nay! and Nowhere to Run are weaker here since this matchup is a grind decided by resolving and protecting threats rather than countering or shrinking individual creatures.
