Card Tips:Junk Sleep
- This card can be searched by "Pharaonic Advent", "The Despair Uranus", and other generic searchers.
- This card's effects can be useful in Decks that rely on Flip monsters, such as "Charmer", "Krawler", "Penguin", "Shaddoll", "Subterror", "Tindangle", and Empty Jar Decks.
- The same also applies for Decks based on monsters with effects that activate upon being Flip Summoned or flipped face-up, such as "Ghostrick".
- During the opponent's End Phase, this card's End Phase effect can be useful for flipping its controller's own problematic monsters face-down, such as "El Shaddoll Winda", "Invoked Caliga", a "Barrier Statue" monster, etc., in order to enable their own plays during their upcoming turn.
- This card can be useful for flipping its controller's "Timelord" monsters face-down during the opponent's End Phase, preventing them from being shuffled into the Deck during their Standby Phase.
- This card's End Phase effect can be useful for cards such as "Destiny HERO - Plasma", "Relinquished", "The Atmosphere", and "Thousand-Eyes Restrict", as they are all monsters capable of equipping only 1 monster to themselves at a time. Flipping them face-down with this card's effect (usually during the opponent's End Phase) will destroy the monsters that were equipped to them, allowing them to equip another monster once flipped face-up again.
- This card's End Phase effect can be useful for flipping monsters face-down that would leave the field during the End Phase, such as "Majestic Star Dragon", "Mirage Knight", some "Neos" Fusion Monsters, Spirit monsters, and monsters affected by "Instant Fusion" or "Limiter Removal".
- While this card's effects can be useful for resetting the drawbacks of certain monsters' effects, such as "Indomitable Fighter Lei Lei", "Giant Orc", and some Level 4 "Goblin" monsters, those monsters will be vulnerable to attacks while in face-down Defense Position, thus being dependent on the opponent Normal/Special Summoning a monster, in order for this card's effect to trigger and flip them face-up again.
- This card's End Phase effect can be useful for flipping Trap Monsters face-down (that still treat themselves as Traps), since they must be Set in the Spell & Trap Zone as a result, allowing them to be activated again during the following turns.
- In particular, "Crusadia Krawler", "Dimension Reflector", the "Golden Land" Trap Monsters, "Apophis the Swamp Deity", and "Statue of Anguish Pattern" can benefit from this.
- This card can still be somewhat useful in "Paleozoic" Decks (whose Trap Monsters do not treat themselves as Traps once Summoned), as it Sets them in face-down Defense Position, which permanently dispels their self-banishing effects (even if flipped face-up again).
- While this card's effect can also have synergy with "Flip Flop Frog" (useful in the Deck for its status as a Level 2 monster), flipping "Paleozoic" Trap Monsters face-down will prevent them from applying their immunity against monster effects, has the risk of flipping their Xyz Monsters face-down (if present), and "Imperial Iron Wall" produces a similar result without these downsides.
- This card's End Phase effect can be useful for granting protection from "Needle Ceiling" (used by either player).
