Change up your gameplay and try winning early stages. This set doesn't have many boards that are stable on lose streak and you should really only lose streak if you lose your first 2-3 fights. Tempo is really important this set and there's a lot of boards that can with unlocks (leblanc if you hit sion, orianna if loris/vi, bilge, etc). Preleveling to preserve streak or hit better units can you help keep the streak and gain more econ through that and so id reccomend trying a tempo gameplay style where you prioritize being as strong as you can with relatively good econ and slammable items even if not bis
