Valakut Exploration is basically a personal Howling Mine for landfall decks, but it can potentially draw multiple cards if you make multiple land drops
Your Leader determines the type of cards you can play the same way a legendary creature determines your color identity in MTGs Commander format
Both the face commander Dina and the old Dina, Soul Steeper care about lifegain and sacrificing creatures, and Beledros Witherbloom herself helps to contribute to that theme really well, not to mention payoffs like Veinwitch Coven and Blight Mound (both reprints from the OG Strixhaven precons)
Additionally, the deck is easy to understand, making it an excellent choice for introducing new players to the world of Magic: The Gathering Commanders
Instants usually go directly into the graveyard after they resolve
Its surprisingly good in certain Affinity decks
