>>37402355This is looking much more in my favour. Starter was also Ghost type. Lots of opponents have been Ghost type, too, but I was lucky enough to catch not-Scyther in Route 30 (having missed my route 29 catch to a ghost sunkern) with Foresight. Falkner's bug Pidgeotto was a bit of a pain, but nothing significant.
BSTs are changed as part of the randomisation process, so (un)fortunately Scyther isn't very gamebreaking.
