We are going with one of the flagships of the main set of the Light element.
It is the Black Dragon, an indomitable beast capable of devastating the battlefield with its breath of fire.
It has 1 attack point that is countered by its 7 health points and its cost of 3 crystals.
In addition, it has the abilities "Flight" and "Fire Breath 2", which make it unaffected by attacks from creatures without "Flying" and inflict 2 points of damage each turn to the card in front of it before attacking and change the attack type of all damaged enemy cards that have Shot for Basic Strike.
