This episode is...interesting. Mostly the second part of the test reminds me of the Battle Factory, in which you have to use rental pokemon.
For pokemon league qualification, first off, it was just one badge, so acing all the tests wouldn't automatically get you into the PL.
Second, the second test makes sense with having to do with the PL because it's testing the trainer's abilities to be flexible, to be knowledgable of other pokemon's abilities & attacks, and to be able to adapt to new situations in battle.
But the first part of the test, I agree, was pretty pointless. When you're doing nothing but battling in the PL, how would knowing which way the spiral on a poliwrath's stomach turns or what Jigglypuff looks like when seen from above help you in battle? Also, probably the only people who'd even stand a chance of passing this test would be the MEGA-FANATICS who spend hours just staring at (and possibly also talking to, LOL) pictures of pokemon, memorizing every single minute detail.
That "Jigglypuff seen from above" question was hilarious! I'll bet every single freakin' person in the whole room got it wrong, and that's why they all fell over. I love that falling over thing; it's one of the most hilarious aspects of anime.
Well, that's my opinion on this episode. It was good as a filler because it put a unique, never before seen spin on the pokemon world and possibly also served as some of the inspiration for the dynamics of the Battle Factory in Emerald Version.
