Cyber Stein isn't a meta card. They don't limit a card base on meta status. Masked Change is indeed broken when you start with 4000LP and your opponent can activate 3 per turn.
Dear Players,
We will consider limiting Masked Change after we release Masked Change II in a new meta changing Structure Deck EX.
- Thank you for playing Duel Links!
