This is the deck I through together for the Throne Winter Invitational and ended up going 11-4, Rank 2 (at least temporarily).
Honestly, both in normal Throne and in this event, the meta feels pretty wide open, which was nice to see. And when the meta is wide open, aggro is a great option and so it was with this.
A few notes: Everything was useful and helped me win games - that being said, I did just throw this together, so I'm sure the numbers could be optimized. Same goes with the marker, except for perhaps Jennev Merchant, which I have yet to grab (the idea was to prevent power flood by providing a follow up aegis unit, but it just never came up - thanks to emblems, power flood never really happened. Otherwise, I used each card at least once, but that isn't to say there aren't better options.
Best of luck out there!
