Guinevere vs Masha

When playing Guinevere against Masha, focus on utilizing your mobility and crowd control to kite her effectively. Stay at a distance and use your first skill, Magic Shockwave, to poke and zone her when she approaches, while saving your second skill, Energy Wave, for when she commits to an engage. Once you have your ultimate, use it to lock her down and deal significant burst damage, especially after she uses her skills, as Masha is vulnerable during her cooldowns. Position yourself near walls to maximize the effectiveness of your ultimate, and be cautious of her ability to chase; disengage if she gets too close and wait for your cooldowns to come back up before re-engaging.
