Gigaheart, Invincible King Sword/Ohginga, Strongest Passion (#V1a)
:
* A creature equipped with this gets "speed attacker" and can't be destroyed while attacking.
* Dragsolution - When any of your Dragons attacks, if that is the second Dragon that attacked this turn, after the attack, flip this card to the dragheart creature side and untap it.
* Speed attacker
* Whenever this creature attacks or whenever your opponent chooses this creature, put a dragheart creature that costs 10 or less from your hyperspatial zone into the battle zone. That creature gets "speed attacker" until the end of the turn.
