What is the proper procedure and penalty for forgetting to put out your chosen champion and only realizing during the first turn of the game?

Ruling: This is a deck presentation error that results in a warning. If caught by the opponent after hands are drawn (rather than by the player who made the error), the penalty is upgraded to a game loss.

Sequence:

• Judge determines if the correct state is easily obtainable
• If easily obtainable (e.g., champion can be retrieved from deck), restore the correct state and issue a warning
• If correct state is not easily obtainable, upgrade penalty to game loss

Nuances:

• At low-level organized play (like Nexus Night), penalties should be lenient as these events are for players to get familiarized with the game
• The specific process for restoring correct state is not defined in the rules document and is left to judge's discretion
• Who catches the error matters: if the opponent catches it after hands are drawn, it's a game loss; if the player who made the error catches it, it's a warning
