I would include Windfall and maybe Memory Jar for more draw/discard and also Mox Diamond, Chrome Mox and Lotus Petal to get the commander out faster. Trinket Mage, Voltaic Key, Mana Vault, Grim Monolith and other Targets like Pithing Needle, Grafdigger's Cage and Engineered Explosives could also be interesting.

Winterblast: Hey thanks for your suggestions. Fast mana was originally in my plan but was scrapped due to a slower gameplan of not rushing out Bruna but playing hatebears first. Will consider them again after further playtesting. Thanks!

Hey, I really like this!

I was wondering about the inclusion of Vryn Wingmare over Thalia. Is it because it has flying?

nemoforever: Yup! Flying gives it an edge over Thalia.
