"Combination Attack" Rating Score by ダイナソー紅月

His Quick-Play Spell that can be followed up by disarming the Union.
Monsters equipped with Unions can be attacked again, and of course Unions that have been unequipped can also be attacked, so you can attack at least 3 times when equipped. Needless to say, it is meaningless unless it is activated during your own battle phase.
The problem is that many unions have low ATK. There is no meaning unless you use a union with a certain amount of ATK, such as a cavalry dragon or 《Machina Gearframe》.
Monsters that can equip Union also have difficulty with his ATK, mainly early ones.
If you use it, the newer Union is the best, but even Dark Sword & Cavalry Dragon is 1800 and 2000, so you can expect it to be relatively cheap. If you can attack directly, you can blow away 6500 LP, so I'd like to aim for it.
The two in the illustration have low ATK, so compatibility is bad.
Don't forget that if you're already equipped that turn, re-equip Union in Main Phase 2 to reduce the chances.
It doesn't make sense if the RBI of the two monsters is low, but depending on how you use it, you can play an active role. It is also interesting to use it when the opponent's field is empty to decide the finish.
