I've been using Manaphy with Sticky Web. Manaphy sets up so easy in SW and is nearly impossible to stop. Its easy to add partners to prevent defogging / spinning too like Taunt Thundurus, etc. Timid Manaphy OHKOs Exca which is nice, and then there is the matter that Mana easily breaks stall teams since its coverage at +3 is near impossible to switch into, and most stall defoggers / rapid spinners give it free set ups.To be honest, I haven't had any issues against it either. I know everyone is saying it's a really good Pokemon, but maybe it's just my playstyle that has made it mostly a non-issue to me. I usually run either pretty offensive teams or bulkier teams with tons of pivots because I hate not having the upper hand. Still, I tried playing with it tonight and was so underwhelmed with it lol. I know it's not the case because it's a Water-type with good bulk, but I felt like I didn't get any opportunities to set up with it. Maybe it was just the opponent's I played. /shrug
Anyway I've never ran it outside of SW, but I have to say that using Manaphy is super easy when you use it in SW (assuming you are skilled enough to keep SW up). It gets so many set up opp. and can literally just click one of its coverage moves and destroy the entire metagame. Its bulky enough to live every priority attack in the game too at 100% which is a great feat in and of itself.
I'm not sure Mana is "broken". Under SW, I'd say holy fuck yes. However, keeping SW up isn't THAT easy, and it's a team support option offered to a lot of Pokemon, so I digress.
