regardless of when u get maril, it's still top tier material. All it does is OHKO sh1t
If you're saying that Azurill OHKOs things, then let me point out every other Normal type you can get that has at least 40 Base Attack.
Lillipup has Base 60 Attack. It doesn't OHKO shit, even with Return.
Patrat has 55 Base Attack. It doesn't OHKO shit.
Remember people bashing Purrloin? It has 50 Base Attack. AKA, more than Azurill with Huge Power.
Azurill is utter trash when compared to other Normal types you could be using. I really want to know what sort of Pokemon you were "OHKO"ing with Azurill, and what level, because if something with nearly DOUBLE its base Attack can't OHKO things, then how can Azurill? Stating that you get an early Marill doesn't mean much when the only thing that Marill has any use for is killing Wild Sandile and Darumaka in the desert. Again, I am NOT hunting for a Huge Power Azurill when having one really doesn't make a difference in the long run.
Scraggy is difficult to find, but it utterly destroys the E4 with its duel STAB and is a reliable Gym killer for the entire time you have it. Without Moxie, its still pretty damn good, getting early HJK and the game being nice enough to give you an early Wide Lens.
Magnezone has 13, count em, 13 Resistances. It also has decent bulk, and its easy to find a Sturdy Magnemite, meaning that Magnezone usually gets one free hit in against something it shouldn't be fighting anyway.
Darumaka hits like a truck, and outclasses every other Fire type in terms of availability and sheer power.
Azumarill, no matter where you get it, does none of these things. It doesn't utterly thrash most of the Gym Leaders (Scraggy doesn't fear Clay, Drayden, Colress, GHETSIS (which is huge), Marlon, your rival, Grimsley, Caitlin, Shauntel, and Iris (though he'll need a bit of help)) Top tier is for things that make the game infinitely easier, and babying an Azurill that CANNOT OHKO THINGS EVEN WITH RETURN OR FRUSTRATION does. What happens if Azurill DOESN'T evolve at Level 17? You're stuck with Azurill for another couple of levels.
Let me make this clear, if PURRLOIN is being considered for Bottom Tier, and no one wants to use it, then what does Azurill have over it? Evolving to get something you can find in the wild fairly easily just when you need it?
What I'm reading, is someone who love Azurill way too much. I would much rather have something that contributes something to the team, such as...you know...Mareep, Magnemite, or Riolu...or you know...Lillipup.
It's stupidly easy to find Lillipup. It's not so easy to find a Huge Power Azurill that doesn't have any use for a good portion of the game.
Arguing Gothita for Mid, too. It has better bulk than Reunicles and is faster. I didn't have much trouble using it at all, and it was generally useful for the whole game. Getting Energy Ball and Charge Beam was nice. I feel that wherever Reunicles is, Gothitelle should be right next to it.
