Surprisingly enough, Four (Costume) actually makes a good Power-Up Enhance card considering she's just a DRA card.
While you'll need some Buffs to power up her Skill, she works out quite well and just as powerful as any standard Enhance card.
Pretty much a standard 15% Skill Boost. But if you manage to get a Straight+, then you also get +1 ATK.
