Whenever a player casts their commander or attacks with their commander, they may say "Only one may stand." If they do, that commander becomes a Knight in addition to its other types until a player planeswalks away from Game Knights Live.

Knights you control have double strike and trample.

Whenever chaos ensues, commanders you control can t be blocked this turn and gain "Whenever this creature deals combat damage to a player, draw a card" until end of turn.
