You gave me such good recommendations for Myra that I was wondering if you might have some insight for me? You see I'm looking to build an adventures commander deck! While I'm looking for overall recommendations for an adventure deck, I'm actually looking for some other kind of input... As I don't know if I want to build Gorion, Wise Mentor or Beluna Grandsquall?
Can't speak of these two, my Adventures deck has been led by Extus for a couple years now!
Generally speaking, white and green will have the most good adventure cards so far, which would lead you towards Gorion. However, it's important to note that the cost reduction from Beluna I'd value more than the copy from Gorion. Copying the spells is powerful, but the main issue that arises when playing adventures is that the cards are bad and inefficient on both sides.
While Gorion remedies the problem by making the spell half better, Beluna remedies it by making the permanent half cheaper, and as such less inefficient. This leads you to wanting to play both halves of the card to get your value, and as such actually do the thing Adventures promise. Both of them are worthy payoffs, Gorion just lopsides the deal on spells' side.
Something really neat with adventures is that you can interact with them like creatures, which makes them easy to get back to hand from the battlefield or the graveyard, to be able to reuse the spell. You can't do that if you cast the spell half and then it sticks forever in exile because the creature is just bad to cast.
So, personally I'd lean towards Beluna out of these two, but if you want an experience more focused on the spellslinging half, Gorion is a fine choice.
