no, the theme was "Sumo", which in itself is okay
I dare however ask how exactly Magnezone fits the bill. It might be heavy, but it also floats, has no limbs, and is generaly just a chunck of magents, rather than a sumo fighter, who is heavy mostly because he is fat, like snorlax.
We will see about that once he posts his choices.
ICBM: nice try to make a team entirely of OU, however:
Volcarona is decidedly orange, not red.
Brelloom (I assume you meant the shiny form) is also orange.
Ferrothorn in it's shiny form has red vines...that's it. The clearly dominating color is this greenish-yellow of the shell.
Red has to be the absolutely dominating color, not just a small highlight, like weaviles headress thing, or ferrothorns vines. I am a bit disappointed that despite the post explaining this tournament that this tourney is about themes, so one should go with the pokemon that are the most red, as red as they can be. When making a choice here, the choice is not "which strong pokemon have some red on them" but "which red pokemon are strong" or actually "which mons are the reddest". It clearly said that this was non-competitive, why else would I carry unfezant and tropius, if not for their deliciousness. Certainly not for their competitive strengths...
Scizor, shiny Gyarados and Latias are very red, and perfect choices. Volcarona and Brelloom are very borderline. I would have considered them if there wasn't even "Orange pokemon" as an option on the list, or maybe if there were no other choices. Ferrothorn is just not red. Maybe 15% red.
Just looking around, very red, maybe the most red would be Darmanitan, the king of red. Also Parasect, Rotom-H, Bisharp and Krookodile and maybe Octillery. Blaziken is also allowed, if it doesn't use speedboost, an ability that would put it in ubers.. Among the shinies, an obvious choice would be Dusclops, Skuntank or Scoliopede.
You are not starved for choices here.
I made the first round non-competitive to bait gain the interest of new players and expand the league, wouldn't be cool to steamroll over their clearly non-competitive themed-teams with a team of only OU powerhouses. Every team has some strong and some weak mons.
If you find that boring, rest assured that the next tournament will contain competitive teams. As a preparation for it, I will offer anyone who hasn't played competitive before help in teambuilding, and those who ask for it can even subscribe the more experienced players as advisors during tourney battles, to level the field a bit.
In our first tournament, the competitive teams (mostly mine) absolutely annihilated all opposition, and that's not really fun, Dwarmin even quit because of it.
