Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Thanks for bringing that up, actually. In addition to the association with priority users and good flavor fit with Malaconda's cunning nature, Feint is also a nice little nod to Infiltrator. It wouldn't have occurred to me to add that before but now that I think about it I like it a lot!
