I don't see why Scarf Chandy doesn't full out attack, since if it doesn't it's locked into a non-damaging move allowing Toxicroak to set up more. Any calcs for how much a +1 Sucker Punch does to standard Chandelure?
I think he might have been saying Chandelure is an example of a ghost that does all out attack (AKA ghosts that don't behave like Scarf Chandy beat Toxicroak). Anyway, to answer your question, a Chandelure with no defense investment is always OHKO by Adamant Max Attack +1 Sucker Punch whereas a non Attack boosting nature will deal 94.6%-111.4%, a OHKO after pretty much any residual damage.
