"only XL-3"

Please provide a clear interpretation of the rules for trading colors! I don't have much experience with this, and I haven't heard any specific suggestions yet: let's be clear and concise!

Clearly and concisely: the colors need to be assigned in the tables to determine the turn order. To avoid confusion, it's better to use colors other than red and blue, such as white and green. Then, we slightly change the order of the items in the regulations:
2. XL templates: 8mm6a, 8xm12a, 6LM10a, 8xm8a, Spider.
3. Standard draft template selection: green starts, white makes the last choice.
4. Castle selection: random pair + trade
The host generates a random pair of castles using a special button. Immediately after generation, each player can request a regeneration once for 500 coins, which the opponent pays. If at least one castle is repeated during regeneration, the same player can (but is not obligated to) request a free regeneration until a new pair of castles is generated.
5. Trading for color. (who starts doesn't matter)
