I am looking to borrow an EUW account around Silver V.

I am wanting to boost an account that is Silver V on EUW, however this account has poor mmr and I need to duo with a friend in order to carry these games out.

I would like to borrow someone's account on EUW and use it to duo. Essentially you will be getting a free boost; I will be boosting both accounts up 1 division.

If anybody could help me out, that would be great!
