  We discuss a new classical action that enables efficient computation of the
gluonic tree amplitudes but does not contain any triple point vertices. This
new formulation is obtained via a canonical transformation of the light-cone
Yang-Mills action, with the field transformations based on Wilson line
functionals. In addition to MHV vertices, the action contains also
$\mathrm{N}^k\mathrm{MHV}$ vertices, where $1 \leq k \leq (n - 4)$, and $n$ is
the number of external legs. We computed tree-level amplitudes up to 8 gluons
and found agreement with standard results. The classical action is however not
sufficient to obtain rational parts of amplitudes, in particular the finite
amplitudes with all same helicity gluons. In order to systematically develop
quantum corrections to this new action, we derive the one-loop effective
action, in such a way there are no quantum contributions missing at one loop.
