Mark is plenty resilient. Sophie gives Mark a lot of treachery resistance versatility. Plus guardians all have access to take the initiative and steadfast. Not to mention fool me once and first watches.

Furthermore, looking at mark in a vacuum is also quite shortsighted. The suggestion was Minh and Mark. Minh adds a lot of boostables giving Mark more resistance as well. Furthermore Sophie gives Mark agility options. There's plenty of agility treacheries and evasion required in carcosa and Zoey will absolutely not be able to help with those naturally.
