The two archetypes are in different formats (Landfall in Standard, Jund Sacrifice in Modern), so a direct head-to-head matchup isn't meaningful. Let me check if there are Landfall or Jund Sacrifice archetypes in the same format, or if the question is format-specific.
I can see that "Landfall" resolves to Standard (Mono Green Landfall and Selesnya Landfall), while "Jund Sacrifice" is in Modern but is a very minor archetype there. These two archetypes don't share a format. Let me check if there's a Jund Sacrifice in Standard.
Both archetypes exist in Standard. Let me now get the matchup data for the most relevant Standard landfall variants vs Jund Sacrifice.
Here's what the data shows for Standard (both archetypes share this format), looking at the last two months:
Jund Sacrifice vs. Mono Green Landfall (the dominant landfall variant at 12% meta share): Jund Sac has gone 5-3 in 8 matches, a 62.5% winrate. That's a meaningful edge, though the sample is small. The trend holds across other sacrifice flavors too — Rakdos Sacrifice is 8-2 against Mono Green Landfall, and Golgari Sacrifice is 6-2. Sacrifice as an archetype family is consistently beating up on Landfall in Standard right now.
Selesnya Landfall fared even worse, going 0-4 against Rakdos Sacrifice in this window (no recorded matches against Jund Sac specifically). The pattern is fairly consistent: sacrifice strategies appear to have a structural advantage over landfall in the current Standard meta, with Mono Green Landfall sitting at 40% or worse across most sacrifice matchups.
One caveat: the head-to-head sample sizes are small (8 matches for Jund Sac specifically), so treat these numbers as directional rather than definitive. Worth watching as more data accumulates.
