How was Mamoswine rushed? They even had it cost Dawn a contest.Without a doubt Charizard. Not only was it the first one, but Charizard disobeying Ash had the more serious consequences - he lost in the Pokémon League because of it. Dawn and Iris? Nothing that serious. Also, it was only when Ash saved Charizard's life that the lizard decided to finally obey Ash; and before then, it had random moments where it wanted to battle by itself (Like VS Blaine's Magmar).
It's hard to rank either Mamoswine or Excadrill above the other, because quite frankly, they both sucked. Mamoswine's just seemed way too rushed, and Excadrill's was pretty much forgotten about until the Georgia episode.
For me, it just felt like it was resolved a bit too soon since there was only about a fourteen or fifteen episode gap between where Mamoswine refused to listen to Dawn to where it was resolved. It felt like Dawn didn't struggle as much with Mamoswine as she could have if the issue was expanded a bit more and there was possibly a bit more buildup to Mamoswine's attitude changing through some interactions with Dawn. I think that the only buildup we had prior to that episode where Dawn and her team helped it was how it was getting a bit more interested in Contest battles.How was Mamoswine rushed?

Swinub-Pilowine-Mamoswine didn't take that long at all. There was only 20 episodes of it as a Swinub (and it hardly appeared during those 20), and only 3 episodes as a Piloswine. Ash's Charmander obeyed Ash for 32 episodes before it evolved into Charmeleon; and during those 32 episodes, unlike Swinub, it was used quite a bit. So we actually saw Ash bonding with Charmander, then BAM, it evolves.How was Mamoswine rushed? They even had it cost Dawn a contest.
Just because it was an old Pokemon doesn't mean that they couldn't have advertise it more through battles and interactions with Dawn and/or the rest of her Pokemon. They promoted both Aipom and Cyndaquill fairly well, despite both being from the same generation as Swinub and only Aipom having an evolution from the then recent fourth generation. Outside of the Giratina movie, I don't remember Swinub doing that much, if at all, prior to the episode where it evolved. They clearly gave it to her show she could have a Johto Pokemon that evolves into a fourth generation Pokemon and so it would disobey her, but they definitely could have had Swinub used much more often prior to its evolution so that I'd actually feel sad about the change in their relationship and thus feel more invested in the storyline.Why would they need to advertise an old Pokemon like Swinub? It was clearly just there for a while to show it obeyed Dawn. The Mamoswine story itself was handled fine, the ONLY problem is Mamoswine never got a full battle to itself afterward. It was always in double battles.
Charizard was handled the best, but Mamoswine certainly wasn't handled badly.
