Okay, here's my thoughts I experienced throughout watching the episode:
-It sounded like Musashi yelled Megayanma's name in the beginning (from the distance), but when they all got closer, it was Kojiro!!
-More random upbeat BGM they've been using lately, yay!!!
-Shinji?? Your appearance was rather sudden, yet anticipated (yeah, thanks preview...)
-Wow, samurai, you've come a long way since almost 600 episodes ago, you'er now able to manipulate wind patterns?? (There's no other way he could have won with what he had)
-Along come the most obvious two victors for the final match.
-Hey, Dark Pulse in japanese is Dark Aura!!! (I think)
-Goodbye Mukkubird, you will be missed. (I'm not going to lie, it was my favorite of his pokemon)
-Awwww, Shinji's worried about Mukuhawk learning Close Combat.
-Hikari, I'm warning you, don't call out all your pokemon, it's a stupid idea!
-WHAT DID I SAY?!?!
-It all makes sense now, everytime Satoshi wants to evolve a pokemon, it just needs to fight Donkarasu!!!
And that's pretty much what went through my mind for the 2X minutes spent watching.
