Sorry, but I'm going to reject this.
I don't like really Scarfsbuck... its very weak for a revenge killer outside of Double Edge. I'm talking cannot even always OHKO Rampardos with a STAB Horn Leech a weak. You kinda need the Sap Sipper boost to deal damage, and all it can really revenge kill is Omastar and Lilligant, the former of which it cannot switch into very easily anyway due to frailty. The fact that it somehow cannot always OHKO a Magmortar with Earthquake really, really doesn't help, and something with actual bulk is going to take advantage of a bad lock.
That and the write-up is still a bit subpar - its not telling me why I should use it outside of revenge killing those two Pokemon and most partners and move descriptions are a bit lacking. There isn't really much detail or flow.
QC Rejected 2/3
Edit: DC already rejected so i guess this is two?
