theres a good chance his ogre did have ice beam, he just chose to use hydro pump considering it does more to ferroSome nitpicks.
No ice beam on kyogre....... wtf
Random useless switching against ferro cost him the game. Ghostceus could've sacked itself by spamming judgment and chipping ferro to death instead of random switching. Terra was neutered at that point.
i believe he was switching out becuase he was not achieving much ground with leech seed draining, but yes he probably could have played that better
