Mono Green Landfall wants to ramp lands and grow huge threats like Mossborn Hydra and Mightform Harmonizer. Heritage Reclamation is a flexible answer: it can destroy Earthbender Ascension or Sapling Nursery before they snowball, or exile a card from a graveyard (such as Esper Origins) and draw a card. Soul-Guide Lantern slows their graveyard-based value from Esper Origins' flashback and Icetill Explorer's play-lands-from-graveyard ability. The sideboard Strategic Betrayal is a modest edge: they choose which creature to exile, so expect to lose a mana elf or small creature rather than their biggest landfall threat, but it also exiles their graveyard, which shuts off Esper Origins' flashback. Duress is weak since most of their threats are creatures it can't take, and Winternight Stories is too slow against a deck that can out-ramp our card advantage.
