• This clock tower is based on the Elizabeth Tower, which is more commonly referred to as the Big Ben.
  • In the anime, the materialized clock tower is shown to strike 3, 6, and 9 o'clock for the first, second, and third Clock Counters placed on this card (respectively), finally striking 12 o'clock and vibrating ominously when the fourth Clock Counter is placed.
  • This card is the first Field Spell Card to have an effect that applies exclusively to its controller.
