I've been writing down every TM while playing. The ones I'm missing are: 8, 15, 23, 31, 49 and 50. At this point I don't mind if any of you guys "spoil" it for me.
I beat the Elite Four (yeah I raced ahead, sorry again guys) and started on Cerulean Cave. Also started levelling a Jolteon. I'm planning to bring trade my pokemons over onto my save in Gen 2 when we start playing that, just because that seems like a cool thing to do.
My Gengar totally carried in the final battles. He's just strong against everything. Hypnosis + Dream Eater combo works on most every pokemon, he also has Confuse Ray + Night Shade which (it seems) there is no resistance against. His Speed and Special stats are ludicrously high, even when he was Level 52 and squaring off against Agatha's Level 60 Gengar, he still got to go first. He's an absolute powerhouse and it feels like cheating when he fights for me.
