This is not necessarily a good deck in Throne, even if that's where it's for. This is a glorious gathering deck that can sometimes win in other ways too. It's fun if you've been wanting to win via Glorious Gathering and it does it's job efficiently. I could see making room for Calibrate by cutting a couple merchants (Nicto/Snowball shuffling is fun and can be useful, but not strictly necessary) and maybe some Prism Stones.
If you have any suggestions or ideas on how to optimize it, let me know!
