Show/Hide Modern PSCTEdison Rulings:
Changes the battle positions of all Attack Position monsters on the field to Defense Position and vice-versa. These positions can't be changed during the turn this card is activated except by the effect of a Spell, Trap or Effect Monster Card. You can activate this card only during your Standby Phase.
●This card must be Set in order to be activated during your Standby Phase. During your Standby Phase you flip up the face-down Curse of Fiend to activate its effect.
●Face-down monsters changed to Attack Position will have their Flip Effects (and when this card is flipped face-up Trigger Effects) activated. This is NOT a Flip Summon, and won't cause Swarm of Scarabs to activate its Trigger Effect.
●VS. Final Attack Order: While Final Attack Orders is active, you can change the Battle Positions of monsters with Curse of Fiend or Little-Winguard, but the Battle Positions are immediately changed back to Attack Position by Final Attack Orders.
●VS. Destiny Hero Diamond Dude: You can't activate the effect of Curse of Fiend, because it can only be activated during the Standby Phase.
