Odin's Eye (LC5D-EN202)

Once per turn, during both player's Standby Phase, you can select 1 face-up "Aesir" monster you control. If you do, negate its effects until the End Phase, and look at either your opponent's hand or all Set cards they control. Your opponent cannot activate the effects of Spells, Traps, or Effect Monsters in response to this effect's activation.
