[RATE MY TEAM] Sweet Baby Failure- My First VGC Team

[MARSxVenom]

So I have been wanting to get into VGC for a while now and I finally decided to build a team. I had a little bit of help, but a lot of it was what I thought fit and how I wanted to play it. As you can see in the title this is indeed my first ever VGC team. I know it isn't perfect and I am open to criticism for what you think fits better where. without further ado, i present to you my first ever VGC team titled, Sweet Baby Failure

I really wanted to base my first team around M-Venusaur since it is, in my opinion, the strongest mege in the meta game right now. Suicune is a very nice supportive mon and I still like the idea of tailwind even though it is not as popular anymore. Terrakion is mainly there to make sure mega kang is kept in check, while also providing nice coverage for charizard and talonflame as well as heatran. Garchomp is there as a good offensive mon, but is definitely one that I would be willing to change if anyone has a good suggestion. Thundurus is an amazing supportive mon who plays great offense when holding the life orb. Heatran is the most expendable mon on the team as it is there for the sake of having a fire move and is really just a placeholder, it has not done much for me since i put him on the team but I still like his spot being there and could not find anything fit to replace him.

So that is a brief summary of my team, feel free to critique it in what way you see fit as it is my first team and i am still trying to fit into the meta game in VGC. Hope you guys enjoy and have a wonderful day :D
