• "Solemn Warning" can be a menace against Pendulum Summoning, as it will stop ALL the monsters being Summoned at once, destroying the strategy in one swoop.
  • Generally speaking, it is better to use this card in a Deck with multiple "Wiretap", since if your opponent attempts to Chain "Wiretap" to your "Solemn Warning", your "Wiretap" against their "Wiretap", and the 2000 Life Points spent won't go to waste.
