Chess Rules

During their turn, a player may choose one:
• Castle: Exile a card from your hand. If your
commander returns to the command zone, play
that card without paying the mana cost.
• Promotion: Exile a token you control, then cast
your commander without paying the mana cost.
• En Pessant: All tokens you control have
unblockable until the end of your turn.
