OK LET'S GO

1. head to head match with the black organization (episode 345)
   I LOVE BLACK ORGANIZATION ARCS!!! and this arc has all of my favourite characters and i'm a big fan of the artstyle at that time!!! the episode had me on the edge of my seat the entire time and i love the character development jodie got (even though she was fumbled later on) and the way vermouth was introduced. i love the heiji and yukiko moments and sonoko looked soo cute and the fact that vermouth literally protected conan from the black organization despite knowing he's shinichi and so much more but i'll try to keep this short because if i were to continue talking about this episode i'd write an essay and i want to list other episodes. i think i talked about this episode on my priv before though so i'll try to find the post and post what i wrote individually!!! this is my favourite detective conan episode of all time the rest of my favourites don't even come close

2. the mysterious passenger (episodes 230-231)
   ARTSTYLE AGAIN I REALLY LOVED THE ARTSTYLE BACK THEN!!! vermouth protected conan and that was so sweet and the akemi flashback made me soo sad. i liked the jodie moments a lot too and i also really liked conan's outfit for some reason

3. contact with the black organization (episodes 309-311)
   ARTSTYLE!!! AND HAD ME ON THE EDGE OF MY SEAT THE ENTIRE TIME ESPECIALLY AT THE END I LOVE THIS ARC SO BAD I WISH AOYAMA WOULD MAKE MORE RISKY ARCS LIKE THIS we all know nothing will actually happen to conan because he's the main character BUT STILL. MAN

4. reunion with the black organization (episodes 176-178)
   I LOVE THE ARTSTYLE!!! i really liked their outfits and haibara looked so pretty in this episode it was so visually pleasing to me. and i really like how conan and haibara's relationship developed and this was shiho's first appearance too

5. the desperate revival (episodes 188-193)
   the artstyle, i really liked the idea of conan being in the hospital for some reason, haibara, heiji helping out shinichi by pretending to be him infront of ran and i'm a heishin enjoyer, THE HUG!!! and more shinran moments, idk everything about this arc is likable

6. shinichi kudo's new york case (episodes 286-288)
   ARTSTYLE!!! shinichi case and cute yukiko and shinran moments!!! vermouth and akai appearance!!! and i really liked shinichi's quote at the end. and the way vermouth started calling shinichi and ran her treasure after that and even protected conan from the black organization IT'S SO SWEET

7. diplomat murder case (episodes 48-49)
   heiji introduction. also conan turns back into shinichi for the first time and that was awesome. also i am a heishin fan

8. the moonlight sonata murder case (episode 11)
   OH THIS EPISODE BROKE ME no detective conan culprit will ever affect me the way narumi did and the way narumi affected conan too and the end of the episode ohhhhhh

9. murderer shinichi kudo (episodes 521-523)
   i really liked the concept of the episode even though knowing aoyama i had a feeling it wasn't actually shinichi i still really enjoyed the episode. also the fact that heiji noticed shinichi before a dead body had me giggling as a heishin enjoyer. also i really like the idea of shinichi having amnesia and killing someone for some reason idk

10. black impact! the moment the black organization reaches out (episode 425)
    ARTSTYLE!!! i love the way kir was introduced too like nobody would've guessed kir was actually a black organization member when they watch the episode for the first time i literally jumped when i realized this was an important episode

i'm basically a bug fan of the old artstyle from episode 150-500 ish and the black organization arcs
