!! Daily Double !!
Red Vivi Leader Locked +4k Counter Event and Yellow Nami Leader Locked Searcher Event
Despite there already being a 4 cost 6k power vanilla whitebeard pirates character from OP02, this OP03 character was a significant boost to the whitebeard deck when it was released.

A blanket reduction to the opponent's entire board? Better out this guy fast or your board isn't sticking for the rest of the game!
Kuzan
1 cost red hair pirate that can activate main and -3k a character and kuja pirates counter event that gives +4k and can bounce a friendly character back to hand
Building Snake Dance (Building Snake + Snake Dance)
Despite releasing as late as EB01, this 5 cost 7k vanilla still saw some play due to being one of the few cards that could be cheated out by the 4 cost Hiyori of the same set.
Mountain God
This 2 cost character has the unique effect to draw one card as an on play with no additional cost. No other 2 cost character does this.

Three-Pack Hum Soul Franky Swing Arm Boxing Solid (Three-Pace Hum Soul Notch Slash + Soul Franky Swing Arm Boxing Solid)
Surprising that an OP13 card could still be useful as a 5 cost 7k vanilla, but I guess its typing allowing you to cheat it out for one don for a certain leader was enough.
