Unity.

Select 1 monster on your side of the field. The DEF of the selected monster becomes equal to the combined original DEF of all face-up monsters on your side of the field, until the end of this turn.

There can only be 1 face-up "Earthbound Immortal" monster on the field. If there is no face-up Field Spell Card on the field, destroy this card. Your opponent cannot select this card as an attack target. This card can attack your opponent directly. Once per turn, you can inflict damage equal to half this card's DEF to your opponent. If you do, this card cannot attack that turn. Also, if this card is in face-up Defense Position on the field, your opponent cannot conduct their Battle Phase.

 

Discuss the usefulness, if any, of this combo. Some Level 10 build (is that a thing?) With Malefics and Gustav for big Defense and extra burn? I really don't know.

Not good, certainly not good, but HOLY FREAKING CRAP THAT IS HILARIOUS. Toss in Destiny Hero Defender for more damage, or just tech unity in Samurais for OTK potential.

What about using them in a Super Heavyweight Samurai deck since that would work well in combination for the Unity boost specially from Big Benkei with its 3500 DEF.

You mean like this?

For Heavyweights, I find D2 Shield to be more reliable.
