Early game · first 8 minutes
Remove a turret when you can do so without giving McGinnis a free gun trade. Keep your bishop threatening her approach, and avoid standing where Spectral Wall can separate you from your lane partner.
Solomon vs McGinnis
What's giving you trouble?
Full matchup plan
Mid game · Walkers
Fight from cover that lets you leave Heavy Barrage's target area. Protect the ally McGinnis can shoot and use healing reduction when Medicinal Specter sustains the group; a root alone does not interrupt her barrage.
Late game · Patron
Spread out when McGinnis starts Heavy Barrage. Reach solid cover and attack from another direction. Move the queen toward her only when teammates can follow; the rooks do not interrupt her channeling.
