From lists on this site

The snapshot follows public Union Arena tournaments. Sung Jinwoo, Hajime Saito, Shin Asakura, and Rei Ayanami are the names that keep showing up. Everything else is a step down or a title specialist.

Solo Leveling - Sung Jinwoo Midrange · Tier 1
Highest power ceiling and resilience combination in the format via the Sung Jinwoo raid chain and Shadow Monarch recursion
Evangelion - Rei Ayanami Tempo · Tier 1
Top-tier consistency (80) combined with strong tempo makes it the most reliable Tier 1 deck to execute
Evangelion - Evangelion Test Type-01 Pseudo DMS Phase Tempo · Tier 1
Very high consistency (79) rivaling the Tier 1 Rei Ayanami build
Rurouni Kenshin - Kaoru Kamiya Midrange · Tier 3
Among the most consistent midrange decks via near-full playsets across two namesakes
Sakamoto Days - Shin Asakura Aggro · Tier 1
Elite tempo and consistency combination puts it among the format's fastest, most reliable decks
Chainsaw Man - Denji Aggro · Tier 2
Deepest Denji redundancy in the CSM cluster ensures reliable curve-outs
Chainsaw Man Aggro · Tier 3
Denser front-line curve than most midrange decks, punishing slow starts
Rurouni Kenshin - Hajime Saito Aggro · Tier 1
Highest tempo score in the meta, defining the format's aggro ceiling
