Well, I encountered quite an amusing glitch this evening.
Forge’s Ego is so big it’s taking over all the other leaders in Blitz:
Here’s me being the Shipmaster in Blitz 3v3
Then here’s me being Atriox,
Notice something strange with my army? Banished in disguise, as well as the cards.
For some reason, Forge’s deck would be used despite me selecting different decks throughout the evening.
It fixed itself when I the Blitz screen and then jumped back in.
