Returning player - smurfing and LF duo to diamond

Hey there. Came back after a long break from the game. Before I quit I was plat 3 on a different account, and I quit because I got bored and was playing a different game very seriously at the time. I think I can easily hit diamond given enough games, I just want a competent duo partner of any role to play with so I can make that climb faster.

The account that I'm playing on started at silver 4 this season, and I have climbed to Plat V promos in about 200 games with a 57% winrate, though I haven't really been tryharding that much so I think with a duo partner we can easily achieve a 70% winrate together given we have good synergy. I am open to playing almost any champ and any role to suit the duo's needs so champion synergy isn't an issue.

I have been playing this game for a long time so I have a very good understanding of macro-level play. I'm generally pretty good at shotcalling and have experience doing so, so discord for voice communication is required. I want someone who is serious about winning, but at the same time no ragers or socially awkward people please.

Add me in-game with the username "Abaki" or on discord with the tag "Vreezi#1540" if you're interested. Thanks.
