This card can be useful against Gladiator Beast Decks, since your opponent won't be able to tag out after they attack it.
If it seems like your opponent may Special Summon monsters during their turn, you can use a card such as "Desert Sunlight" to delay that.
Using "Ceremonial Bell" to check an opponent's hand is a good way to plan when to flip this card.
This card can be splashed into a "Prediction Princess" deck - it combos extremely well with "Prediction Princess Tarotrei" who can Flip this card during your opponent's Draw Phase and re-set it or re-summon it from Grave in your own turn to be used again. Additionally, it can be searched by "Prediction Princess Coinorma".
Similar to its potential use in "Prediction Princess" decks, "Junk Sleep" can be used to flip this card face-up during the opponent’s turn.
