Qirin instead of Dino Nest to help get to 5 power quicker. Also, Dino Nest is a lame card and deserves to die to relic removal.
Musket to kill Plunk and get our units out earlier.
Solfire instead of Searing Fist because it gives us the option to go face at the end of a game.
Halotipped Spray mostly for Inscribe, but also to go face and clear out relic decks.
Chizue partly for card draw, but mostly because I like him.
Talir Headmistress could be an interesting addition if you have it. Charge fits in with the theme of this deck, and our Unleash cards can make use of the additional power. Maybe take out Chizue, and replace it with 2 copies of Talir and bump Sindain up to 4 copies. With Talir in the deck you could also lean more into a midrange strategy by replacing Duster with Dunehill Clan.
