This card can be Summoned or Set and activate a card to Nuke all monsters such as "Dark Hole" or "Torrential Tribute" to have it destroyed. Its effect would then activate after "Torrential Tribute" or "Dark Hole" has resolved allowing yourself to use the Special Summoned monsters to Xyz Summon and attack directly.
"Call of the Haunted", "Limit Reverse" or a similar card could also be Chained when your opponent activates either of those cards for a similar effect. On your turn, an Xyz Monster can be Xyz Summoned, and on your opponent's turn, there will be monsters on your field to defend yourself. Remember that the monster Summoned by this card are destroyed during your End Phase and not any players', so if they were Summoned during your opponent's or teammate's turn they will remain on your field.
Note that if cards like "Chain Destruction" are used when this card is Summoned to destroy copies of this card in the hand or Deck, 1 of their effects can be gained, since its effect can only be used once per turn.
Use this card along with "Honest" to destroy an opponent's monster, itself, and get the two monsters from its effect.
Summon this card while "King Tiger Wanghu" is on the field; "Wanghu" will destroy this card instantly and allow yourself to gain its effect right away. Be aware, though, that this only works when the monsters that was Summoned with this card using this method have ATK of more than 1400, otherwise the cards that was Summoned will be destroyed by "Wanghu".
