- You can't Tribute Set using the ① effect.
- In Edison, there can only ever be 1 face-up Field Spell on the field.
- If you control this, and you activate another Field Spell: This card is destroyed, and its ② misses its timing.
- If you control this, and your opponent activates another Field Spell: This card is destroyed, and its ② activates (it does not miss its timing).
- If you Set another Field Spell while this card is in the Field Spell Zone (face-up or face-down), this card is destroyed, and its ② effect can be activated. You can read more about Timing here: https://www.mikamika.de/edison-rules
