Good for taking down monsters with higher attack when you have more monsters.


  • Limited usability since it can only be used to destroy enemy monsters but not able to deal damage to LP.
  • Riryoku is more easy-to-use.


Cards that can be summoned quickly/easily but unable to attack like Paladin of White Dragon and Ritual Foregoner are very effective when used together. Cards that can be special summoned with a fairly simple condition like Caligo Claw Crow and The Fiend Megacyber can also be used along with Union Attack. Some other known popular combos are Gravekeeper's Vassal with 2 monsters with a total attack of at least 4400 ATK to achieve the "more than 5000 damage dealt" assessment. As of now, Gravekeeper's Vassal is the only card that has perfect compatibility with Union Attack as it nullifies the drawback effect of Union Attack.

Exactly. It blows! At least it isn't some really rare card from a deck at the shop you would have to try and waste all your gems to try and get. But still quite rare. I have been screwed a number of times because I didn't have this card needed for beating some duelists.
