Anyone else doesn't know what to do with Mega Gren? It gives me crippling choice paralysis lmao. Too many good moves and so little slots.
Run it like you would Ash Greninja but replace the pivot move with Nasty Plot.
Volt switch doesn't make contact so you can't really punish it getting mindlessly spammed unlike Turn and Flip, and things like Parting don't make progress. Basically it becomes a completely free unpunishable click that also maintains momentum AND makes progress.
First of all, Parting Shot is arguably the best Pivot move of the 4 mentioned. Not dealing damage pails in comparison to letting deadly sweepers have an easier to set up or keeping more health on your breakers. That’s way more impactful than some chip damage.
For Example Mega Greninja goes from being KO’d with hazards up to tanking and having some health to spare after Clefable is at -1
0 SpA Clefable Moonblast vs. 0 HP / 0 SpD Greninja-Mega: 236-278 (82.8 - 97.5%) -- 62.5% chance to OHKO after Stealth Rock
-1 0 SpA Clefable Moonblast vs. 0 HP / 0 SpD Greninja-Mega: 156-186 (54.7 - 65.2%) -- guaranteed 2HKO after Stealth Rock
This either lets Greninja use Nasty Plot or KO a weakened Clefable depending on if it just switched in or was using Moonblast.
Second, hazards exist. And if the ability is tied to a Mega, that means you can’t wear HDBs and have to use a Mega Stone. Additionally you’re also taking damage any time you switch into an attack. So it’s not like pivoting moves go unpunished.
It’s also not like U-turn or Flip Turn are instant win buttons against teams that don’t have contact punishment, nor is Volt Switch once you remove the opponent’s Ground type or if they had a Ground type to begin with.
