Early game · first 8 minutes
Leave Arctic Beam's line before its slowing effect makes retreat difficult. Move a bishop through Kelvin's approach, then shoot from cover rather than trying to win a long gun trade under the beam.
Solomon vs Kelvin
What's giving you trouble?
Full matchup plan
Mid game · Walkers
Watch Ice Path's route and protect the ally Kelvin can reach. Pressure a position your team can contest without following him onto exposed high ground, and use healing reduction when his healing is the problem.
Late game · Patron
Keep enough distance that Kelvin cannot trap you alone inside Frozen Shelter. Wait for the dome to end before attacking an objective it protects, and move the queen into position for the fight afterward.
