- Normal Spell Cards have "Spell Card" written on the top.
- They have no symbol or text indicating they belong to a specific category.
- Normal Spell Cards can be activated only during the Main Phase (either player's), unless they have specific exceptions stated in their card text.
2. Quick-Play Spell Cards:
- Quick-Play Spell Cards have "Spell Card" written on the top.
- They have a lightning bolt symbol in the top-right corner.
- Quick-Play Spell Cards can be activated during either player's turn, even during the Battle Phase or Damage Step, unless they have specific exceptions stated in their card text.
3. Continuous Spell Cards:

- Continuous Spell Cards remain face-up on the field and apply their effects continuously until they are destroyed or leave the field by some other means.
