If I understand correctly, on the left is Red, and on the right is Blue.
3. The template is chosen by crossing it out from the list of 9 templates: 2SM4d(3), Balance, skirmish-standard (at 200% difficulty with the HW_rules_mod patch, if both players want, you can play a mirror match, Jebus cross, Mini-Nostalgia, Diamond, 8mm6a, 6LM10a, and Spider. The player marked in red in the table starts crossing out the template.
4. Choice of castles... The choice of castles in this tournament will be "at will," meaning there is no specific crossing-out process – if you want to play Necropolis, please do; if you want to play Dungeon, go ahead. BUT... you cannot play the same castle more than 2 times in the tournament (if this rule is violated, the player will be temporarily disqualified; if it happens again, they will be disqualified).
The red player starts choosing the castle. If the players want to play with the same castles, they must agree on who will play which castle; if they cannot agree, they will play with random heroes.
This point is not open for discussion; if it doesn't suit you, don't play.
