For one, they are almost all over priced
Seat of the Synod is the king of the colored lands, because blue is the color that works best with artifacts, and Vault of Whispers is second because of Disciple of the Vault, but all of them have joined the fun at one point or another
Plaza of Heroes Adding utility lands to your mana base improves your decks consistency by maximizing the number of cards that affect the game you can squeeze into your deck without affecting your ability to curve out
Full of flavourful adaptations, deep cuts, and stunning art, Ive personally never seen as much hype for a set as this
Besides that, Surtrs just a 5/5 with trample for 5 mana
I didnt get caught out on much with this set list, but cards like Abupt Decay and Scavenging Ooze now likely represent failed specs that I would be happy to sell at or near cost, given how long they might take to recover past potential
