Manectric is cool, and does keep up the line, yeah. As for Galvantula I'm the spider-finder and mover of the family. If one appears, I'm the one who gets it out of sight. So a huge electric spider is no problem for me...
Abra/Gastly require trades - I already have Kingdra/Scizor for that.
Bisharp is cool, but tbh he gets rushed so easily, and Pawniard is hard to train...
Don't worry about rambles, rambles make everything non-rambly fun.
