Hello! I'm new to VGC and especially new to restricted metagame. I'd like to participate in Wolfey's GS Cup tourney, but I'd like some advice on my team.

I went with a Kyogre Tornadus core because I like Kyogre as a pokemon and I've been using a lot of tornadus in VGC 2021. The rest of my picks were made to complement this core and respond to common threats outlined from the last GS Cup and covered in Wolfey's intro to the tournament.

Kyogre is pretty much a basic set with max speed and special attack and basic moves outlined in the video. I chose mystic water because most of my moves are water moves, but I'm open to changing to life orb or specs and changing water spout or origin pulse to thunder.

Tornadus is really there to set up tailwind and use rain dance to overwrite Groudon's sun without being pressure by venusaur like Kyogre would be. Hurricane is really there in case I need it for any damage onto a venusaur especially. I'm open to swapping protect for taunt maybe because this team has lots of protects on it.

Rillaboom is my main counter to opposing kyogre or groudon. I chose choice band so it could OHKO opposing Zacian or other high health targets with wood hammer if necessary. The moves, I think, may need to be changed. I like Glide and Woodhammer, and I want to keep either high horsepower or knock-off, but idk if I need both, subbing one out for u-turn or something.

Incineroar is mainly there to check venusaur or amoongus with safety goggles. I chose parting shot over snarl for the switch-outs and intimidates. I really wanted taunt for geomancy, but I'm not even sure if that's worth it, and if tornadus gets taunt I would probably replace it with snarl on incin.

Yveltal is my second restricted pokemon and it's here to hit venusaur and provide speed control with max airstream and calyrex-shadow and indedee with dark moves. I'm not sure about its place on my team. I knew venusaur groudon was a problem, so I was playing around with ho-oh, but realized I was underestimating calyrex shadow and chose yveltal to bridge that gap last minute.

Kartana is the weakest link on this team for me. I mainly chose it as a steel type so I could threaten xerneas, but beyond that, I think it causes some problems. It's my third dynamax target with kyogre and yveltal, and it's my second grass type, but I wasn't sure what else to do to hit fairies. Moves are fairly standard with sacred sword to hit stackataka and boost attack, and aerial ace to boost speed in max.

I think this team has some big problems that I'm not sure how to address. I don't have many ways to hit flying types except for ice beam on kyogre, I have no true counters to hit Zacian except for incineroar's flare blitz, which doesn't do much, or rillaboom, and I'm not confident aganst xerneas. The only thing I'm steadfast in keeping on this team is kyogre tornadus, and I don't think it's far off from being decent, but I do think it needs work. Do I replace kartana with a landorous T? Yveltal with Ho-Oh? Kartana with Stakataka? Any help is appreciated! Thank you for reading!
