Seeing that link (well, a related link about who to use the three 6* tickets on) reminded me that Dogwood (yukata) is a decent RG option as well. Festivalwood is similar to Habranthus (one-time damage negation for the squad along with a strong counterattack, +attack, and 1.2x skill proc) except with +skill damage and +defense in place of Habranthus' added hit/pierce/magic coverage.
