I got a Noctowl set that I find that works really well. Since Noctowl is in the UU tier, and this one works as a support in a way too, it should do pretty good in a team. It's in smogon's form in a way so yeah (I made it myself, even go check ANY site and you won't find the set unless it's by me.)
Saba-san's Special
Noctowl@Wide Lense
Nature: Bold
Trait: Insomnia
EVs: 252 HP; 132 Defense; 124 Special Defense
Hypnosis
Roost
Air Slash
Reflect
This Noctowl works as a great support character and works as a fair special wall. It can used Reflect then Hypnosis for a free switch-out. It's also pretty fair at whittling down the enemies health while they sleep, depending on what the opponent is. Most people wouldn't use a Noctowl in BL or OU tiers because of its poor defense, but this set can work fairly well in both. Roost is there to heal when you desperately need it.
Damage Calculations
Standard Electivire w/Expert Belt - 49.50% - 58.17% damage – With Reflect
Standard Electivire w/Life Orb - 53.71% - 63.37% damage – With Reflect
Standard Electivire w/Expert Belt - 99.01% - 116.58% damage – Without Reflect
Standard Electivire w/Life Orb - 107.43% - 126.49% damage – Without Reflect
From these calculations, you can see that if you get a Reflect in, you'll survive every time. Depending on how the Electivire's IVs are, it will determine whether or not you survive without Reflect.
