• "Royal Decree" can still be destroyed with Trap Cards that are Chained to its activation such as "Dust Tornado".
  • This is excellent in a beatdown Deck, as the most used Trap Cards are based in the Battle Phase.
  • When getting powerful monsters on to the field like "Judgment Dragon", it is a good idea to activate this card before the Summoning, so the effects of Traps like "Bottomless Trap Hole" can be prevented. That way, the field can be cleared and almost guarantee the effect/attack will land successfully. It's a good idea to use this tactic later in the Duel when it is ready to end the Duel, because your opponent has most likely exhausted their use of "Mystical Space Typhoon" or "Dust Tornado", which could Chain to the activation of "Royal Decree". Using this strategy too early is more likely to be countered. Keep in mind that there are a few cards that can counter the assault of your monster that are used for attacking, namely "Gorz the Emissary of Darkness", or even "Battle Fader". However, cards like "Sky Scourge Norleras" which cause both players to empty their hand can easily eliminate that risk.
  • It should be recommended that this card be activated after your opponent activates a dangerous Trap like "Mirror Force". That way, back up Traps in reserve can be kept and use them on your opponent's turn.
  • It's highly recommended at least have your back up Traps Set due to the fact that this card is highly vulnerable to destruction and Traps are hard to recover.
  • Using this card with "Arcana Knight Joker" eliminates the need for Trap Cards for the effect of "Joker", so focus on having your Monsters and Spells.
  • On top of negating the primary effect of "Fairy Box", it can cancel out the LP cost for it and effectively forcing your opponent to send it to the Graveyard.
