>>29925387I tried to answer that question myself yesterday.
I examined all the legendaries and spent hours finding counters and doing calcs.
Here are some of my key findings:
I think the island guardians are overrated aside from Tapu Lele. Tapu Lele is highly underrated and will be one of the most powerful pokemon at VGC. All but 3 of the legendaries have a 1-trick-pony moveset and some, such as Xurkitree, rely on Hidden Power to round out their coverage. The UBs are more threatening in general than the Tapus.
The Tapu Koko + Politoed opening is overhyped and easy to beat. Many counter-openings work and won't ruin your team building.
Tapu Koko is a barely-threatening pokemon forced to use its lower attacking stat to carry out its best strategies. It has poor movepool.
As for what the meta will generally be like, I feel it will be an offense-favoring meta. Weather wars will not be as prominent as people now think.
The most dangerous pokemon will be Tapu Lele, Pheromosa, Xurkitree, Kartana.
One strong opening will be Tapu Lele + Pheromosa. Fake Out will be less important than ever due to the best Fake Out users being banned.
Intimidate will be less important than ever due to most of the top threats being Special Attackers.
Overall this vgc represents a huge shift in the way that Doubles is played.
>The average team will look like: 4 pokemon spent on the team's own "winning strategy," 2 pokemon used for specific counters to UBs, Tapus.
1 pokemon in the "winning strategy" group must be able to 2HKO most Legends.
Nearly every team will need a Choice Scarf user of base 83+ speed that has the ability to OHKO Pheromosa.

Feel free to ask clarifying questions. Will post important anti-meta pokemon following:
