When effects refer to your 'chosen champion', does it apply to any card with the same name and title, or only the specific physical card you designated? Also, when do you select your chosen champion - is it fixed on the decklist or chosen each game/match?

Ruling: Effects that refer to your chosen champion apply to any card with that name and title, not just the specific physical card originally designated. This avoids tracking issues with multiple copies.

Nuances:

• The timing of when you select your chosen champion (whether it's fixed on decklist, per match, or per game) has not been officially stated in tournament documentation yet
• Setup rules use "reveal" rather than "pick/select" which may imply the chosen is predetermined
• A recent video suggests you can choose which champion to play at the start of your game if you have multiple champions of your legend, implying flexibility between matches or games, though this could be a script oversight
• In best-of-3 matches, current understanding is you cannot switch which champion is your chosen between games, but this awaits official tournament documentation
