Nah, you just need a weapon with First Strike. If it's not on Yuna, you can just keep her out of the party and swap her in first turn and it's the same as if it had been Yuna who had the First Strike weapon. Of course make sure Yojimbo has overdrive, it massively increases your odds.

It is recommended to increase your compatibility with Yojimbo (i.e. fight random battles with him and have him perform Wakizashi and Zanmato as often as possible, and Daigoro as little as possible; never have him die, never give him 0 gil) until he uses it very regularly. Remember to always give him gil in powers of 2, otherwise you're just wasting your money. I usually give him 128 Gil in random encounters.
