The entire verse seems like a bit much.
- Bruleé creates reflections that do everything the triad does and keeps them distracted.
Doflamingo hits them with parasaito, which requires class T lifting or higher to get out of (and the triad's best has class G) and forces them to walk into the mirror dimension and stand there until every mirror is smashed, then gets out through the last one and it gets destroyed too. Dark triad gets taken out via BFR.
- Fujitora pins them with gravity (class T again) and they stay stuck. Moria takes their shadows in daylight and they get erased from existence.
Alternatively, Fuji pins and Sugar touches all of them. Doll triad. No one remembers they ever existed.
- 3 days prep? Then Cracker claps thousands if not millions of gear three level soldiers into existence to jump them with an army of Luffy-level cracker soldiers, and while distracted with those, Kuzan Ice Age flash freezes all three. (His freezing creates ice continents iceberg thick near instantly) Law slices all three and because the nature of his cutting bypasses regen due to it being technically not an injury, just a form of spacial manip, they get diced. (Unless they can passively resist it while frozen)
- Bruleé reflections, followed by Fujitora class T pin, then a Noro Noro beam to to freeze them in time followed by Blackbeard just sucking them into the Yami dimension and never using liberation to free them.
- Any method of pinning mentioned above, followed by Kuma slapping them to the other side of the planet, or outside of it altogether.
- Again, any method above, and Hawkins creates straw dolls of them. Anything they do to him occurs to each other than himself. If they go for a killing blow, they die or kill each other.
- OR, Hancock petrifies all three with any of the distractions/pin-downs mentioned above being applied
Killing them isn't needed when there are so many methods of sealing, BFR-ing and even an erasure method from Moria that can take them out with no more than 4/5 characters.
