question

[MarkHarvey]

Was playing someone and they basically played N'zoth and C'thun twice during the match. How is this possible?

Yeah, we need way more info to help you. Forstarters, there are 2 different C'thun and N'zoth cards in the wild format (from 2 different expansion). Maybe that's what you mean?

There is a way to record a match and then share the link as a GIF, then we can tell what happened.
