digimon card game special booster 1.5 - Ver.1.5 BT01-03 Uses the simple but unique strategic game system created by renowned American game designer Ryan Miller Digimon Release Special Booster 2.5

You can pay one black mana and sacrifice another creature to have a player mill three cards, which is cool, but you can also pay one life to add one colorless mana which can only be used to cast spells from your graveyard

Lightsworn Monsters are blessed with incredible effects, high ATK/DEF, or both

While it can be useful for stopping specific cards, it is largely to niche to be that useful for a player compared to other spell cards

Lavabrink Floodgates provides opponents with the choice of letting you have some mana acceleration in red or eventually hitting all creatures for six
