***** Attribute: Wind
When this card is Special Summoned: Target 1 face-up card your opponent controls; banish that target. When this card leaves the field: Set the card that was banished by this effect to your opponent's side of the Field.
ATK: 2300 DEF: 1500
There's two ways to Special Summon this card easily without the use of Monster Reborn and Call of the Haunted and those are: Teleport and Brain Hazard. Teleport lets you Special Summon it from your Hand just like Valhalla for Fairies, except you have to pay 800 Life Points. Brain Hazard is the "Special Summon from the Banished pile" Continuous Trap Card. To abuse his effect, you use the Exceed Summoning method which avoids "When this card leaves the field" effect.
So the main idea is:
Space-Time Police + Psi-Beast = Level 5 Xyz
