Flex Queue is not the Practice Tool

I'm trying to get the orianna chroma and got placed Silver 1 for my flex queue. I already knew it'd be a struggle climbing after having to play promos against diamond players, but my top lane aatrox who is playing him for the first time doesn't help. So please, for the love of god, if you're new to a champion, play them in normals or in practice tool. Flex is not the place for you to get the hang of a champ and cause your team to lose.
