What are the playmat layouts that are legal for tournaments? I.e. placement of the main deck, rune deck, legend, champion unit etc.

To ensure clarity and prevent the accidental mixing of decks during high-level organized play (OPL), you must arrange your board according to the layout rules specified in Tournament Rules 508.

Mandatory Board Layout (Tournament Rules 508.1 – 508.6)

• Main Deck and Trash: These must be grouped together on either the left or the right side of your board (Rule 508.4).
• Rune Deck: This must be placed on the opposite side of the board from your Main Deck (Rule 508.5).
• Legend: Must be placed between your non-rune permanents and your Chosen Champion (Rule 508.6).
• Legend and Chosen Champion: These must be kept together on whichever side of the board you have chosen for them (Rule 508.6).
• Vertical Positioning:
  • Runes: Must be positioned closer to you (the player) than non-rune cards (Rule 508.2).
  • Non-Runes: Must be positioned closer to your opponent than your runes (Rule 508.3).

Additional Layout Requirements

• Associations: Each card or indicator that attaches to another must be clearly associated with it physically (Rule 508.7).
• Exhaustion: Ready objects should face you. Exhausted objects must be rotated 90 degrees. All exhausted objects must be rotated consistently (either all clockwise or all counter-clockwise) (Rule 508.10).
• Tokens/Buffs: Tokens must be represented by cards that clearly show their status, and buffs must be represented by objects that unambiguously represent a buff in game terms (Rule 508.8, 508.9).

These layout rules are mandatory for clarity in competitive settings. In high OPL, players must follow these arrangements strictly.
