Target 1 face-up monster you control; add up the total ATK of all other face-up Attack Position monsters you currently control, then during the Battle Phase of this turn only, the monster gains that much ATK, but cannot inflict battle damage to your opponent, also other face-up Attack Position monsters cannot attack.

Rating7.0 /10


  • Good for taking down monsters with higher attack when you have more monsters.
  • Needed in some farming decks, and very effective if used properly.


  • Limited usability since it can only be used to destroy enemy monsters but not able to deal damage to LP.
  • Only selected monster can attack.

Tips, related cards, skills

A well known popular combo is Gravekeeper's Vassal with 2 monsters with a total attack of at least 4400 ATK to achieve the "Over 5,000 Damage" 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.

Gravekeeper's Vassal

Since this card deals effect damage, it can be used together with Union Attack to deal some damage. Used to farm some LD because it can get a high score quite easily by using 2 monsters with high attack, and end the duel with effect damage ONLY.

Spell Reclamation

If you only have 1 Union Attack, you can use spell reclamation so you can use it twice. This will make it so that you can reach 10,000 damage if your total monster's attack is at least 5,000. If you have 2 union attack, then use 2 instead of this.

Mystical Beast of Serket

Used to special summon high attack fusion monsters, and using less cards than 2 monsters + a Polymerization. Blue-Eyes Ultimate Dragon or Master of Oz are the ones often used together with Vassal and Union Attack.

Whait! When did the card start saying "does no damage"? Isn't this useless now?

it has always been like that. it's kinda why people use gravekeeper vassal with it since it can deal effect damage instead.

So I had a question, cuz I mean its supposed to add the attack before the battle phase.
So lets say i have 2 blue eyes, and a vassal.
It would add it and be 6700 then that number should be added during the battle phase correct?
But what if I martyr one of my blue eyes? techincally when the card activated it would still be 6700, but it only adds 3000 at the battle phase? Is this a bug or is the card wording weird?

"add up the total ATK of all other face-up Attack Position monsters you currently control". So if you gift of the martyr 1 BEWD, then u currently control 1 BEWD left with vassal, right?? It is obvious why your vassal just gain 3000 from UA (Union att) because u r currently control just 1 BEWD.

The event is almost over again, and I have lost count on how many times I've farm him, and I still didn't get this card. I'll delete this game If I don't get this card this time. I've just farm him at lvl 40 and I only get some gems and dark stones, I'm f*cking done with this..

Well, I did't get it guys.. It's my second event and I still didn't get this card. But it was still better than the previous event,which I didn't get any UR or SR card. This time the only cards I didn't get were Union Attack and Magical Blast. I'm really upset though, I hope they'll put Union Attack on Card Trader..

The point of the card is to take out a monster. It specifically says it doesn't do damage

Absolutely no one will run it in PVP, its sole purpose is for farming.

I've bought 100 packs of Valkyrie's Rage and only have 2 copies of the Unhappy Girl. Sh...
