requires clarification:

on the Skirmish (200%), Balance (if M200% is chosen), and Anarchy (200%) templates, is the Castle selection still random?

Changes have been made to the regulations:

4. Castle and Hero Selection:
The Skirmish m200, Balance m200, Anarchy (200%), and Ёлка templates are played with full random selection.

All other templates: Castle bidding. The host generates a pair of random Castles using a special button. Immediately after generation, each player can request a regeneration once for 500 coins, which will be deducted from the opponent. If, during regeneration, at least one Castle is repeated, the same player can (but is not obligated to) request a free regeneration until a new pair of Castles is generated.

Mirror templates: Hero bidding. Before the bidding begins, each player has the right to ban 1 hero, after which the bidding starts. The player playing with the red color bans first and makes the first bid. After the bidding, each participant secures the right to use one of the selected heroes as a starting hero. If a restart is taken, the player has the right to change the starting hero to any other hero, except for the opponent's hero, which was chosen after the bidding.

Also, clarifications have been added for playing on mirror templates:

Additions and clarifications for the h3dm1 and mt_diamond templates:
- Time limit per turn (19:00+08:00+01:15)
- Medium roads.
- Allowed to pass by shifted guard posts.
- Redraw is prohibited, as there is no bidding for color.

Can the veto be changed depending on the player you are playing against? Or is it the same for the entire tournament?

As in the previous tournament, the veto must be communicated to each opponent before the game; it can be changed.
