What's giving you trouble?
Full matchup plan
Mid game · Walkers
Attack after Paradoxical Swap misses. Send rats and use Royal Pestments for her return fire while you get into range.
Late game · Patron
Spread out around the banner so an upgraded Paradoxical Swap cannot swap several teammates into the enemy team. If someone is swapped, shoot Paradox as she arrives among your teammates.
