In my opinion, Corsola is a complete disaster. Its movepool sucks, its stats are even worse, and its design just doesn't appeal to me at all. Seriously, it's a pink coral with a smiley face and an adorable cry, can you take it seriously? I mean, you walk into the Battle Spot/Pokemon Showdown, you bring out your Gyarados, and
that is what they chuck at you? It's honestly a wonder how people even find it cute when in reality it was done into a disservice, to the point that I don't see it as very cute.(Maybe it's because I'm more used to working with more dangerous-looking 'mons like Druddigon or Dragalge.)
Competitive-wise, it's utterly useless in the metagame and even outclassed in regular play. It was evidently designed to be a wall, but its defenses aren't even that high and its stats are worse than
Onix. Its typing is horrid(a double weakness to Grass plus average defenses leaves it a sitting duck), and Carracosta is a
much better defensive Water/Rock type if you ever feel like adding one. Its only chance of injuring
anything is a set consisting of something along the lines of a Choice-Band+Hustle-boosted Head Smash with 252 Att EV's and an Adamant nature. That sounds great, and indeed, it would be great on anything else. Defensively, it doesn't even fare well at all(especially nowadays with heavy-hitters such as Bouffalant and Dodrio returning to the NU/PU tiers), since they can take Corsola out easily with their coverage moves(Dodrio can even OHKO Corsola with Jump Kick,
even with its type disadvantage). Corsola's defensive movepool is also barren, consisting solely of Recover and, to a lesser extent, Mirror Coat(but good luck surviving ANY special attack), plus Regenerator if you include abilities.
Outside of battle, I hate how Corsola is excessively rare(ESPECIALLY in Gen 7, took me 2 days to find that bastard); in other words, a Pokemon that will eat away at a good chunk of your patience, time, and sanity, and all you get it this trollish grin staring at you because you wasted so much time finding it. All it's really good for is finding Mareanie.
I can now conclude that Corsola was designed to be the world's cutest wall. Well, that's horseshit, because it does
not look cute, and it
definitely is
not a wall.
Special mention goes to Farfetch'd, Unown, Luvdisc, and Delcatty, but I felt I would go off rambling about Corsola first before I start tackling the other useless abominations.
Let me ask you, does that look like a stone-cold murderer(no pun intended)? I'll admit, when I first caught Corsola, I named it Bonesaw because I thought it would be great in battle.
Guess I was wrong.
