Hi everyone! I'm almost level 30, and I want to do really well in my promos so I can get into a good division. I pretty much play support every game, and I want to probably play it in ranked. What would you say is the best champion to play to get a decent standing in the ranking system? Also, any little tips and tricks are appreciated! Thanks

Play the champs you're best with!
your main and the one fitting the team comp. A tank champion if no tank. A Ap kill lane if your team is full AD. The most important is your comfort then your synergy. A bit of luck is also appreciated;)
Nami fits with and against any combo.
Just ban Yasuo.
your main just that but since i don't know your main i would say leona or thresh
Leona and Janna are amazing if you can play them well. I've had insane amounts of success on zyra in ranked... Like I have a 70% winrate on zyra, and I main her. I have a 100% winrate on janna as well, but I duo with a pretty good yasuo a lot so that helps ;D Janna Morgana and Leona are godly in solo queue.
I use mostly Thresh, Blitz, Lulu and Leona when I support. I recommend having a few supports you can play, so that your one main isn't banned or picked by the other team. Blitz is banned often, so I wouldn't count on him, but use him if possible.
since i don't know your main i'd say leona or thresh they are a beast in soloq
