Duels

Cool! One minute, plus casting time – that’s more than enough. Another question. When you’re building a hero specifically for a duel, what information do you have about the opponent: is only the race known, or is there also information about the hero – whether they are a mage or a warrior, or is nothing known? If it’s just a duel with another person, then, as I understand it, you just agree on who plays which hero, and that’s it, right? But what about a tournament?
