Once again, I am aware that this is not an actual tier on Showdown or PO, but I use it on 3DS wi-fi battles anyways :/
How it works - Qwilfish, Golduck, and Greninja are sent out first on the left, center, and right, respectively. Greninja is the fastest, so it expectantly uses Mat Block. Golduck is the second fastest, so it uses Simple Beam on Qwilfish, which then uses Minimize, raising its evasiveness drastically. On the next turn, Golduck will Psych Up this, and Qwilfish will either use Minimize again or make a Substitute. After this turn, Golduck makes its own Substitute. Depending on the type effectiveness or damaging possibility, Greninja will either use Dark Pulse or Ice Beam and wait to get Eject-Buttoned out (if it survives), or use U-Turn if it wants to switch out immediately (even though this doesn't do too much). This will be used for Mat Block support later (depending on whether I've used Trick Room or not). Upon Greninja being ejected, either Slowking or Quagsire would be sent out. Slowking might use Trick Room if Golduck is near possible fainting, or to boost Fish and Duck with first-turn Heal Pulse once they get enough protection (they would probably move last if I did this). If Golduck faints and Trick Room has been used, Octillery is sent out. Octillery would most likely use Water Spout while in Trick Room, as loss of HP is less vulnerable. Quagsire could be sent out in multiple situations on the left or right sides, as it is usually not the first target an opponent would choose, but it is more useful in Trick Room. It would use either Curse or Amnesia first, depending on the largest threat. Once it has gained enough defensive boosts, Quagsire is extremely hard to get by, as its only weaknesses are Grass and Freeze-Dry, and if it is being attacked physically, there is a possibility that the opponent would be doing more damage to itself than to Quagsire (Rocky Helmet), depending how many times Curse was used. Opposing stat boosts also won't work on Quagsire because of its ability, Unaware. Golduck's Cloud Nine will also hypothetically prevent any Politoed-with-a-Lapras-using-Thunder "strategy" or any Charizard-Y-and-Venusaur-and-Noivern-all-using-SolarBeam "strategy" because it nullifies the effects of weather.

The main thing I'm worried about is combining two completely different strategies together that might have a negative effect on either strategy. Greninja is basically useless in Trick Room, so I find that that would be problematic. However, I think that combining the two strategies could work in my favor as well.
Also, Moody and Minimize are not banned on X & Y Battle Spot, which this team is intended for. I don't intend to use this team on any online metagame.
Please note that this team is only in an experimental stage, so I'm completely open to any suggestions or criticism.
