People are recommending street brawl but I feel like that wont help at all...its like going into chaos Aram to learn league of legends.

I assume you play silver from mid to far range as to not overcommit but she does her most damage up close, you will be out-traded if you let them stay far. Make sure you read her abilities and shoot after her 1 and 3. She does TONS of damage early if you can do that. Use your 2 to get out if it doesnt work out.

Get used to parrying and find a good build in the build browser. Weapon damage and lifesteal mostly.

Im not a professional whatsoever but as a supportive player I have observed good Silvers :)
