For starters you need Moo Manchu's gear from the tower since the gear there gives Critical Strikes, Leviathan's Call and charges since Buccaneer excels at playing aggressive and tanking. Kane's gear is optional too for Titan's Chorus. Valor's Fortress is a must.

You need a Scent 2 pet at least to help against Swashbuckler's Black Fog since they're relatively common, preferably a loyal pet too so it has a higher chance of showing up. Webs is useful too but situational. Maybe a heal or two for better sustainability. Grants Vengeance Strike/Bladestorm is good too. Grants Relentless is a must. Time Warp is amazing as well, but hard to get.

Generally Buccaneers use Highland Charge or shield themselves or their strongest companion and rush down to the captain or their most threatening companion since it can be really hard to counter a Buccaneer that plays aggressive enough if you're unprepared. I've seen Musketeers and Witchdoctor captains die in less than 4 turns because of this. But sometimes it's not good to rush to the opponent if they debuff you or if they know what they're doing. It also depends on the class you're fighting against too.

Pete is an absolute must, Goro is a good option if you have him, El Toro is good too for his damage, dodge and his buff. Contessa is good as well with First Strike 3 since you can counter Swashbucklers with it since it eats up their hides and Gallant Defense is good too. Barnabus, Ratbeard and Temujin are good options too but I would stick with the first 3 companions I listed if possible.

There's more but that's on the top of my head and those are the most popular picks.
