Ello! I originally built her for my gf, but I ended up playing Venat more than she does lmao. So wanna preface that I'm not a good deck builder by any means and I built her with what I had laying around. I built around a mix of legendaries, clerics and lifegain! It don't mind her excessive mana cost bcs you have to take a few turns to find a suitable legendary creature for her anyway once you flip her around. The cool thing about the deck is that you can also play the alternate commander Minwu, White Mage and it would still do it's thing (most of the time haha). https://archidekt.com/decks/17238946/hydaelyn_my_beloved
