Here's an RBY 1v1 VR. This was put together fairly haphazardly. Not really sure if this VR should count towards the aggregate, given my fairly low activity with this tier, but I felt like making one. I might make some changes later, especially if I get the chance to review the games and usage stats from RBYOMPL.
Some miscellaneous thoughts:

About a week or two into RBYOMPL, I raised the idea that Tauros might just be the best Pokemon in RBY 1v1, and certainly top 3. Seeing the VRs above, it seems like this was not as clever of an idea as I thought. Tauros doesn't have an obscenely dominating matchup spread, but it really truly doesn't "lose" to like... anything. When I watch 1v1 games, especially live ones, I like to predict which Pokemon each player will select, as I assume many spectators do. I was kind of shocked how often I found myself thinking "Tauros is probably just the best bring here." And it seems many players felt similarly, as I feel like I saw Tauros get sent out a lot. As implied above, the only real downside to it is that it doesn't really dominate any one important matchup, so it can be a little weird in the builder. But in exchange, you get to run the get-out-of-jail free card when the matchup looks bad. Tauros is legitimately probably bannable, but I don't think that pursuit is on the docket right now, given the activity of the tier and the seeming absence of complaints so far. I don't plan to petition for this, but the thought did cross my mind.

Snorlax is really good and has a ton of viable sets. Only pointing it out here because of how safe of a bring it usually is. After Tauros, it was the most likely Pokemon for me to assess as the safest bring in a given matchup.

I don't know if it was just the games I remember watching, but it seemed like these two lost a lot. Neither is particularly great into the top 3 Pokemon, all of whom are kind of "safe picks," so I don't think they themselves are great picks overall. I like the matchup spreads of Pokemon like Amnesia Thunderbolt Snorlax, Chansey, or Articuno better, even if they aren't directly comparable. I think Jolteon gets the edge between the two because it wins the head-to-head and has higher BS potential with the insanely high Speed.

I like how the template I used randomly has 3D Slowbro on it. Is this the only true "answer" to Alakazam? Kind of feels like it. Though it is very underwhelming into almost everything else relevant.

Rhydon is basically useless, but it will own the electric-type Pokemon, if you really need to deter them.

Articuno is probably better, but I was actually pretty impressed by what Lapras was able to muscle through during the tournament, especially thanks to Confuse Ray. Silly move.
I may add more comments later, but that's all for now. Cheers!
edit: It's not pictured, but I added Jynx, Cloyster, and Gengar to the end of my VR, in that order.
