Draugr Guards are just normal Draugr, except they come equipped with a shield.
Deal with the shield by performing a shield smash and Guards make for easy prey. The biggest mistake you can make is simply attacking the shield instead of smashing it, as this will cause the Guard to retaliate with its own strikes after it absorbs a few hits.
When the shield is gone, barehanded attacks are a good option — as is the case with any low health opponent. Watch that stun bar build and then finish them quick with a brutal takedown.
