[osu!std] Dio's Bizarre Badgeless Duel

This is a 2v2, ScoreV2, international osu! standard tournament with team size 4. No team member may have any tournament badge on their profile before registrations end. Each team's average rank must be at least 5.000, e.g. average team rank 5.600 is eligible, but average team rank 4.400 is ineligible. Teams are divided into tier 1 and tier 2, with one member from each tier needing to play each map, similar to a suiji-style tournament. Teams must have members all either residing within or with profile flags within the same time zone group. Further information below. The 2 tiers are Tier 1 rank 1-5.000 and Tier 2 rank 5.000-99.999, with no rank buffer.
