King Renly's alliance with House Tyrell through his marriage to Lady Margaery has made the famed riders of Highgarden available to Renly.

However, as happens to the common cavalry troops, their weakness lies in staying locked in prolonged combat. A sensible commander will pay special attention to making the most of the flanking abilities and the remarkable speed of Highgarden's horsemen to attack the enemy's unprotected flanks.
