This card works well with "Raviel, Lord of Phantasms, because it forces your opponent to Normal Summon the monsters they would Set to create more "Phantasm Tokens" to strengthen "Raviel".
This card is useful for archetype Decks that rely on Counters such as "Alien" or "Venom" Decks.
This card is equally as handy with "Destiny End Dragoon" or the "Armed Dragon" series, as it forces your opponent to have their monsters face-up, allowing yourself to destroy them and (in the case of "Destiny End Dragoon") inflict damage.
This card works well with "Morphtronics" because it let yourself chose to Summon them in face-up Defense Position, so there is no need to wait to flip them face-up later.
This card can destroy a Deck that relies on monster effects that require being flipped face-up, such as "Needle Worm", "Swarm of Locusts" or "Guardian Sphinx", as they are unable to get face-down in the first place to flip face-up.
This card can combo with "Unleash Your Power!" to prevent your Gemini monsters from being flipped face-down by the card's effect.
Because this card allows you to Normal Summon and Special Summon (with cards like Premature Return ) in Face Up Defense Position, you don't need to summon it in attack position in order to activate monsters effects or wait 1 turn to Flip Summon a monster.
