Note:
Solar Seal and Lunar Seal have a different slot.
Similar to RDM white mana and black mana

Current seal slot is all mixed up at top of our card gauge
The new one will have a different slot.
Example:
3 slot for solar seal in the right of card gauge
and 3 slot for lunar seal in the left of card gauge
The seal also independent to each other (minor arcana only consume one type of seal which depend on the major arcana card)
