Well yes and no. Dawnwalker is probably the better choice, and even Magus could be better against lots of aggro, but I do like warping HoTV on turn 5 haha. She has nice interactions with Shatterglass Mage too. There are some good relics that can come down on turn 3/4 that are central to the decks they’re in (Horn, Crown, Mask, etc), and if feels good to get out a Shatterglass a turn early. Overall she’s a weaker choice for the 3 mana slot, but I just have a soft spot for her card design and wanted to she if she works well with Brenn. Dawnwalker is definently the correct choice here. Thanks for having a look and asking! Good luck in your games!
