This deck uses the opponents attributes against them to special summon extra deck monsters that can negate spells/traps and monsters by discarding plunder patroll cards but also letting you draw more cards to continue pressing your advantage.
example of a combo
1 activate
plunder patroll shipyarrrd discard Danger!? Tsuchinoko? and add whitebeard to hand
2 special summon Tsuchinoko with his discard affect
3 normal summon whitebeard
4 special summon bluebeard with his own affect
5 link summon blackbeard with bluebeard and Tsuchinoko
6 set plunder patroll booty
7 end turn
8 as soon as opponent summons use booty change the attribute to light (or dark if they started with a light monster)
9 use whitebeard to summon Lys
10 activate Lys and SS whitebeard
11 activate blackbeard and summon the extradeck monster that corresponds to the attribute of monsters your opponent uses and equip whitebeard to it
as you can see this combo will be different based on the attributes of your opponents monsters but you will almost always get out a good monster(s) to negate what your opponent does.
weaknesses
dark ruler no more completely stops this deck from making decent moves.
it is vulnerable to negations
hard to get extra deck monsters if playing against wind, earth, water, or divine.
