Sup everyone my Pokemon name is XMIrage and I was one of the finalists in a Pokemon competition.
My greninja is a unique one, but is a great Pokemon to have as a lead.
Pokemon- Greninja (obviously)
Nature- Jolly (NOt special)
IVs- at least 5, not in Sp.Atk
Item- Focus Sash/ Band
EVs- 252 Atk, 252 Spd, 4 Hp
Stuff- Greninja is a relatively defenceless Pokemon, but with this moveset, it should help alot.
Spikes- Greninja can be used as a setup/ opening Pokemon. With spikes, you are able to outspeed and possible outplay enemies. Protean changes its type to ground, and most players tend to open up with a rotom. THis denies them of the damage from moves like thunderbolt or volt switch, and you get a free layer of spikes
Mat Block- I know, not many use this, but I guaratee this is useful. It shields your entire team (regardless of position in triple battles) or yourself from all attacks, excluding status moves. Though this move has no priority, this shields you for one turn and you are able to see what moves the enemy has which is key to making correct judgements
Shadow Sneak- Really useful move, prefarably over Water shuriken as it isn't as reliable in terms of overall damage. THis also allows you to turn into a ghost type, blocking fighting type moves which woulda been an OHKO for the Water/Dark type.
U-turn- Though Uturn changes it to bug type with a lot of weaknesses, (fire, rock, etc) it allows for a safe switch and is relatively used as a damage source .
Why I didn't include ice beam, its too predicatble, same risk against fighting type as staying in water/dark form
surf- (main move though, but the most predictable move)
darkpulse- also too predicatable
Thank you for reading this and please vote this as a top one so others have a higher chance for seeing it too, I also made various posts for other Pokemon as well so be free to look around
