MY MIND CHANGED!!! I Bought Emotes In Marvel SNAP!!!
While I still believe emotes are overpriced (1,500 I think would be better), they really aren't that bad considering how much gold you get from the season pass and weekend missions now.
You can use them in every deck with any card. There is no restrictions on using Emotes.
Now that custom card border??? THAT'S CRAZY!!! (i still bought one for Cosmo. I'm so sorry)
