A chakra disruption field. It would be an area effect which is proportionate to the amount of chakra I put into casting and sustaining it. The field would disrupt the ability of anybody within the field to mold chakra (it would not affect myself since it is an area effect radiating outward from my own body). The field would also nullify any chakra based attack that enters into the field from outside of it. For instance, if a TBB is shot into my field, it would be nullified. The downside is that any ninjusu or genjutsu I would cast outward from my body would also be nullified (this keeps it from being overpowered). However, I would still be able to enhance my taijutsu with chakra since it wouldn't enter the field. However, depending on the size/duration of the field I may not have enough chakra to augment taijutsu. Therefore, this would be more of a defensive or support jutsu for a taijutsu based squad rather than an offensive jutsu.
