Lifegain's threats are almost entirely white and black creatures and planeswalkers that cost 3 or less, so countermagic tuned for cheap tempo plays is poorly positioned; Spell Snare and Three Steps Ahead come out for proactive discard and removal. Duress can only take noncreature, nonland cards, so it can't touch creatures like Liliana the Faultless or Haliya, Guided by Light. Its real targets are Ajani Resolute, Lunar Convocation, Case of the Uneaten Feast, and Erode, which it can strip before they generate value. Intimidation Tactics covers the creature side by exiling a creature card from their hand. Terminal Criticism stays in the sideboard: it only destroys blue or red creatures or planeswalkers, and this opponent is entirely white and black, so it would have no legal targets. Deadly Cover-Up remains the key sweeper against their wide boards of Enlightened Confidant, Hinterland Sanctifier, and token generators. Strategic Betrayal makes them exile a creature of their choice along with their graveyard, which cuts off the graveyard that Moseo, Vein's New Dean's recursion engine relies on.
