Since I had this set posted in the greninja analysis, i guess ill just post it here as well. U may call it a dumb or mediocre but it's worked for me one multiple occasions. But hey what do I know.
Greninja: Suicide shinobi
#########
Name: suicide shinobi
Move 1: spikes/toxic spikes
Move 2: taunt
Move 3: water shuriken
Move 4: Surf/Hydro pump
Item: focus sash
Ability: torrent
Ev’s: 252 attack, 252 speed, 4 special attack
Nature: naïve
Moves:
Greninja’s high speed, access to taunt, and access to both spikes makes him a great suicide lead. The choice of either spikes or toxic spikes comes down to preference. Spikes are overall the better of the two, but toxic spikes can be useful for some more defensively based teams to stall. Taunt is there to shut down other hazard setters and taunters. The reason torrent is great on this set is because when u combine the focus sash and torrent, greninja can act as a decent revenge killer with a boosted water shuriken, surf, or hydro pump. The classic surf vs. hydro pump is entirely up to preference, although hydro pump is probably the better of the two since it secures more KO’s or damage, and greninja will not be staying in long so the lack of PP isn’t a serious issue. However, if you are shaky about the accuracy, surf can still be used for some moderate damage. And finally, while a protean greninja isn’t suited to use water shuriken, the torrent boost and ev’s provided can give greninja the ability to pick off some weakened foes and break opposing substitutes and sashes respectively. Some other options could include scald and ice beam. Scald gets the torrent boost and has the nifty chance of burning, but the power of hydro pump and surf makes scald inferior in this set. Ice beam is a good choice to allow greninja deal some damage to opposing grass types, and dent foes such as garchomp and gliscor, but without more special attack investment and the protean ability it is overall a subpar option.
Set details:
The ev’s provided are to make greninja maximize water shuriken’s power. The naïve nature is there to make it so that neither physical or special attacks made by greninja are hindered. Alternatively, some more special attack could be used to secure some KO’s with hydro pump or surf if there is a desire to do so.
Usage Tips:
Since Greninja are always protean, it’s important to keep that in mind while using this set. Protean greninja forces a lot of switches, so try to use this bluff to your advantage by setting up spikes on the switch. The focus sash will enable greninja to get off at least 2 spikes for the most part, and using the proper bluff will enable greninja to possibly get off 3. If greninja’s health is low or activates the focus sash, you can use either of your two attacking options to deal as much damage as possible. However, preserving greninja isn’t a bad choice, as the power provided by torrent can make greninja a great revenge killer with water shuriken. However, this should be done when hazards are off the field otherwise you should just try to set up more spikes or try pick off a weakened foe that is already on the field.
Please keep in mind this is not my full analysis as I still haven’t done enough damage calculations for water shuriken
