I've played a bit of the meta, and I figure it's time for me to share some sets I've been having fun with.

Beedrill-Mega @ Beedrillite
Ability: Adaptability
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- U-turn
- Return
- Poison Jab
- Knock Off / Drill Run
Mega Beedrill is, for me at least, the definitive slept-on Mega Pokemon. One of its main features is its blistering speed, outpacing key threats such as Noivern and Tapu Koko. It's biggest asset over Mega Aerodactyl, however, is a really strong pivoting move in U-turn, allowing it to capitalize and build momentum off of what would normally be considered solid checks. Knock Off and Drill Run are also cool coverage, each with their own helpful assets. Fast CM Taunt Tapu Lele is a great partner for it, protecting it from priority RKing while also taking care of Pokemon it struggles with like Zygarde and Poison types like Toxapex.

Entei @ Choice Band
Ability: Pressure
Shiny: Yes
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Sacred Fire
- Extreme Speed
- Stomping Tantrum
- Stone Edge
I don't really understand why Arcanine is considered so much better than Entei. While it has Intimidate and some more unique coverage like Wild Charge and Close Combat, Entei still has higher speed and Attack and the downright amazing Sacred Fire, which has the potential to completely neuter normal Arcanine switch-ins like Zygarde, Gyarados and Tyranitar, even with the reduced burn damage, and it can do this without wasting a slot on Will-O-Wisp. It even has Stone Edge for other Arcanines and Enteis! If Arcanine is A or A+, in my eyes, Entei is A or A- at least.
As for bans and suspects, I feel like the most overbearing threats at the moment are Kartana and Zygarde. The former just slaps on a scarf and massacres teams, while the latter has a bajillion viable sets, now with -atespeed spam potential. I also think Tapu Koko is kinda problematic with its combo of high speed and power, but it's kinda low priority, with the former two threats being much more dangerous and in need of action.
