I'd call this an OTK deck. The combo is essentially a 1-card OTK after some decent setup - focused on Backs To The Wall;
1 ) Activate Backs To The Wall, summoning back four monsters. 
2 ) Overlay two of them (ideally not Enishi) for a Utopia.
3 ) Summon Utopia Ray using the Utopia as Xyz Material.
4 ) Detach both Samurais from Utopia.
4.5 ) Use Enishi to remove any problematic monsters
5 ) Detach the third material.
6 ) Use the other two to make a second Utopia.
7 ) Summon Utopia Ray using the second Utopia as Xyz Material.
8 ) Detach all three Xyz Materials.
9 ) Attack for 8,000.

It's worked pretty well in testing. Even when I don't get Backs To The Wall, I can keep a solid field through the Kizans and toolbox of Xyz monsters.

That's the only thing I could think of at the moment.
