A
themed card idea, because I thought it was time to make one.
Spell
Pharaoh's Curse 2
Change the passive skill of this creature to "whenever this creature activates it's skill, it's delayed by 1 turn"
Another option i considered, based on the mummy film, would be for it to generate an scarab when the creature leaves play, however it didn't really felt like a curse.
Another possibility would be to make the creature "go back to hand whenever it attacks" but that doesn't feel like an effect a pharaoh would put on someone.
