How are Tyrggvy and Vincent the same Prov cost but one destroys any unit INSTANTANEOUSLY as long as they have any status EVEN VEIL or shield, but the other card that used to do that in 2 turns (Tyrggvy) now does even less and VVM has gotten the best new targets in the new Ciri: Nova, defenders and evolving cards, so Guaranteed value if you're not a complete moron.
Different factions are different, NG generally has few wombo combos, has more standalone cards, is themed more on control, etc.
SK is more about the combo and thus, their design and provisions won't be equal.
Vincent being able to instantly kill any unit with a status is good but not broken; either be more careful with your status effect targets or run a deck that doesn't use beneficial status effects very often.
Or soak the Vincent play, count the provision and play the long game, trying to drain NG of their power plays.
