Jund Sacrifice Best Standard Tournament Choice

These are all Standard decks, not Modern, so I used Standard data from 2026-08-22 to 2026-10-06. I'm assuming that's the format you meant. Winrates exclude draws, and most of them sit within a few points of 50%, so treat the gaps as small.

Your top-8 shortlist

Jund Sacrifice: 52.5% over 136 entries. It has the most event wins of any deck here, with 10 first-place finishes. It's 62% against Izzet Spellementals (54-33) and 55% against Mono Green Landfall (37-30).
4c Control: 53.8% over 85 entries, the best winrate on your list. It has 0 event wins, though.
Boros Dragons: 52.9% over 73 entries, with 4 event wins. It's 52% against Mono Green Landfall (13-12), a small sample.
Izzet Spellementals: 51.7% over 243 entries. It's the most-played deck at 13.4%, with 5 event wins. It also loses to Jund Sacrifice.
Dimir Midrange: 51.0% over 147 entries, with 1 event win.
Lifegain: 46.8%, below average.
Rakdos Lizards: 47.6% over only 8 entries.
Izzet Prowess: it hasn't appeared in the data since 2026-08-11, so I can't rate it.

Decks you've seen on ladder

Jeskai Lessons: 56.0% over 16 entries since 8/22, the highest of any deck here but a small sample. It has 243 entries since July at about 52.5%.
Azorius Control: 51.8% over 49 entries, with 1 event win.
Reanimator: 54.5% over 18 entries. I found no "Sultai Reanimator" archetype, only plain Reanimator.
Golgari Midrange: 43.5% over 32 entries, which is poor.
Izzet Pingers/Burn and Izzet/Jeskai PWers: I found no matching archetypes. The closest, Boros Burn and Mardu Burn, have only 1–3 entries and lose a lot.

Takeaways

Based on results, Jund Sacrifice looks best to win an event. It has the most wins and a strong matchup against the most-played deck.
4c Control, Boros Dragons and Jeskai Lessons are decent options.
Mono Green Landfall isn't on either of your lists, but it's the #2 deck at 12.2% presence and 53.2%. Make sure you're prepared for it.
I can only report tournament results. I can't give sideboarding or closed-decklist strategy advice.
