Anyone tried Tail Glow Manaphy on a Trick Room team? I gave it a go a while ago, and it worked out nicely - using a fast U-turn or a Memento/Healing Wish to bring them in safe. 100 base speed with zero investment and a negative nature will underspeed 252 invested base 70s or higher and yet at the same outspeed base 70s without investment. What this means is outside of Trick Room you naturally outpace the majority of stall, and yet under Trick Room you outpace the majority of offense baring things like Azumarill. Then add this to the fact that Trick Room allows you to invest in bulk, which is already a formidable 100/100/100 and even when Trick Room drops you should easily be able to tank a hit or two and hit back with a ridiculously strong water STAB.
Here's the set I enjoyed most:
Manaphy @ Splash Plate / Wacan Berry / Rindo Berry
Ability: Hydration
EVs: 252 HP / 4 Def / 252 SpA
Quiet Nature
IVs: 0 Atk / 0 Spe
- Tail Glow
- Scald / Surf
- Energy Ball
- Ice Beam
I think Scald is a definite if you have the Splash Plate, after rocks it can 2HKO Chansey with 4 HP / 252 SpDef at the +6, plus it also provides the burn chance - enhancing the already very large bulk you have (you can comfortably survive a Revenge Killer Talonflame Brave Bird for example). However if you still want a good chance to be able to get through Chansey and you want to use one of the berries to greatly reduce the damage of an SE hit, then Surf can be a better option (95.7% chance to 2HKO after rocks).
Energy Ball allows you to breeze through things like Quagsire or other water types, a must for coverage. Ice Beam gets through all the dragon and grass types who would otherwise make you unhappy. HP Fire is an option, but all you're really hitting with that is Ferrothorn so you're best not using it.
Wacan and Rindo berries are great - how Trick Room will play out ordinarily is you'll have a two turns of unbridled supremacy (Trick Room, U-turn/Memento/Healing Wish, Tail Glow, then attack, attack) where the opponent has to volunteer pokemon to faint, then after it goes down they'll send in their electric or grass type to revenge kill you. With the nerf from the the relevant berry, they fail to KO allowing you to hit back with sky high special attack - against a fair few teams this secures you 3 OHKOs with the potential to stretch to a fourth with the high bulk. After that, cleaning the rest of the team shouldn't be too much of a big deal. Wacan berries are for Thundurus and Volt Switchers like Rotom-W, Rindo is for Mega-Venusaur (not ideal as you only 2HKO defensive variants with Ice Beam at the +3, but still good for catching the opponent off guard), Mega-Sceptile and Serperior.
I guess things you'll need a hard answer for are: Ferrothorn, Unaware Clefable, Specs Magnezone, possibly Mega-Venusaur and Chansey depending on what you're running, also multiple rounds of priority damage - very little else is going to enjoy what Manaphy is offering. Mega-Lop can be a huge pain by stalling TR turns with Fake-Out, but it can't 2HKO even with rocks so even if it stalls your last TR turn it's going to have to take a +3 Scald.
