Salamence must not appear in many of these, if only because of how remarkably rare Bagon is to catch (you'd need to either repel-scum your way to the back of Meteor Falls in Hoenn, or bet on a solid 1% encounter rate on Alola route 3), and how annoying it'll be to train up to level 55 if you are lucky enough to find one.
