  We report the independent discovery of PSR J0027-1956 with the Murchison
Widefield Array (MWA) in the ongoing Southern-sky MWA Rapid Two-meter (SMART)
pulsar survey. J0027-1956 has a period of ~1.306 s, a dispersion measure (DM)
of ~20.869 pc cm^-3 , and a nulling fraction of ~77%. This pulsar highlights
the advantages of the survey's long dwell times (~80 min), which, when fully
searched, will be sensitive to the expected population of similarly bright,
intermittent pulsars with long nulls. A single-pulse analysis in the MWA's
140-170 MHz band also reveals a complex sub-pulse drifting behavior, including
both rapid changes of the drift rate characteristic of mode switching pulsars,
as well as a slow, consistent evolution of the drift rate within modes. In some
longer drift sequences, interruptions in the otherwise smooth drift rate
evolution occur preferentially at a particular phase, typically lasting a few
pulses. These properties make this pulsar an ideal test bed for prevailing
models of drifting behavior such as the carousel model.
