I feel like after playing it so many times you probably noticed, but boar princess doesn't work with lyresong. At around 20:50 for example I think you could've magic dice's by using boar princess, replacing Voru with Gilded, then lyresong and replaced Gilded again, then used gambler's to kill Mona. You'd use 4 dice for gilded shenanigans but you'd get 6 back (2 from boar, 4 from gilded and 2 from gambler's). Having Timaeus or Yayoi would give even more dice by reducing Gilded's cost, so they are a great addition for any magic dice deck. Take my advice with a grain of salt though, I'm not a tcg expert lol
