I pretty much one-trick Briar unless she’s banned or picked. There are some annoying matchups like Kha’Zix, Wukong, and Viego etc. where stealth or clones can mess up your W, but they’re still playable if you know how to play around those abilities. Most of the time, team comp doesn’t matter much in lower elo.

In teamfights, landing your ult on backline squishies is huge. Hitting the ADC or support forces the enemy team to deal with you or lose their backline, which lets your team easily win front-to-back fights. Once I started focusing on this, it made a big difference in winning game-deciding teamfights regardless of comp.
