No matter which one you choose, they all feature pre-balanced decks of 60 cards using two Ink types
Take a card like Doubling Season, for example, which is an essential Commander card, but currently obnoxiously expensive
When a monster of the player's side of the field is destroyed, this card can be activated by paying the aforementioned life point cost
Then you can lend his strength to challenge some of the mightiest characters your opponent might have in play
Sapphire cards, like Aurora: Dreaming Guardian, have unique effects that can help build strategies and buff other characters
As more boss decks were sorta requested, I thought I would oblige with many people's favorite villain of the yugioh series', the Prince of Atlantis himself
