Number Soul is a very helpful Double Soul in any situation. Not only does it give +10 damage to non-elemental battle chips, but it also fills your folder completely with battle chips! Plus, regardless of efficiency, I think the Doom Dice attack is cool.
I guess, much like in the anime, this Double Soul is much more tactical. Taking the term "Brain beats Brawn" to another level.
