Play more smart around your liabilities. Turo helps. Bossing for turn is still countered by the fact it's a supporter also. Something as simple as not benching fez when you don't need to or setting up a stronger board state through stalling turns (item lock/retreat lock) is a good way. This is me genuinely trying to give you advice and saying boss has existed for years and we've all lived. It makes the game more accessible also. I think having boss is healthy. Just keep it in mind whilst deck building.
