>>57145511Phione might be usable if you put it in a competitive format where the only mons allowed are total shitmons
Within a playthrough, lol (the only game where you can obtain one outside of an event is legends: arceus)
Even if you do get it via trading/events you'll still be better off just using a Manaphy which is an actually good pokemon; oh and did I mention you need a Manaphy to breed for a Phione?
Meanwhile Igglybuff has no redeeming qualities; you've already stated why it's useless in a playthrough, and in competitive, well, here's the only analysis it has on Smogon's dex (for generation 7 little cup; you sure as hell are NOT seeing this in any official format)
>At first glance, Igglybuff has a good HP stat and a wide movepool. However, all of its other stats are extremely poor, and it lacks enough unique utility options to distinguish itself at all from Spritzee.>In a metagame dominated by Fighting-types such as Timburr and Mienfoo, not having that key Fighting-type resistance due to its Normal typing is brutal for Igglybuff, and its abysmal defensive stats are just another reason why Igglybuff is fully outclassed by Spritzee.>Igglybuff does sport Competitive and Fire Blast, but these traits are not enough to warrant its use whatsoever when its overall stats and movepool are so poor.>Igglybuff's best strategy is to utilize its HP stat and access to Wish to chip away at the opposition. It can switch into Defog users such as Vullaby to activate Competitive, but Igglybuff is so poor offensively that it's hard to capitalize on those Special Attack boosts. Overall, Little Cup has Wish passers such as Spritzee that are much more capable of fulfilling its role.what a flattering and positive analysis
