This is a landfall/enchantment-fueled ramp deck, so Heritage Reclamation is excellent against Earthbender Ascension and other enchantment payoffs while also hitting their sideboard Soul-Guide Lantern. Soul-Guide Lantern helps disrupt Icetill Explorer's mill-to-graveyard land recursion and their general graveyard value. Duress can strip a key ramp piece or removal spell before it lands. Shoot the Sheriff can target their creatures since none are outlaws, but the real issue is they don't present must-answer bodies early enough to justify it over more proactive cards, and Hunter's Talent's damage effect is less effective against their bigger late-game creatures, so we trim some of the slower interaction for hate pieces and disruption.

Duress proactively strips their countermagic (Spell Pierce, Spell Snare, We Say Thee Nay!) or removal (Bitter Triumph, Requiting Hex) before they can use it reactively, which is huge against a control-leaning midrange deck. Surrak, Elusive Hunter can't be countered, dodging their dense counterspell suite, and its trample plus card draw when targeted punishes their removal-heavy plan. Hollowmurk Siege is a slower value engine that doesn't affect the board and can be picked off by their many answers, so it comes out in favor of more resilient, proactive threats. Head of the Hunt is fine but less necessary against a deck without an overwhelming go-wide plan, so we trim a couple copies for the Surrak upgrade.

Duress is excellent proactive disruption against this discard/control deck, stripping their own Duress, Requiting Hex, or Bitter Triumph before it can be used against us. Torpor Orb stops creatures entering from causing abilities to trigger, shutting off Doomsday Excruciator's library-exiling enters trigger. Hollowmurk Siege is too slow and passive against a deck full of discard and removal that will simply strip it before it generates value, and Head of the Hunt's exile trigger is less relevant since they don't go wide, so both are trimmed for proactive disruption and hate pieces.
