The real power comes from Aether Vial, a staple of competitive Merfolk lists, getting it into play for 0 mana
I believe the number one reason is the games evolution
Copies start at $38 for this monster, making it the most valuable card across all three of these drops
I think this pairs best with partner commanders that either add card advantage (Tymna the Weaver) or access to colors with ramp (Jeska, Thrice Reborn or Reyhan, Last of the Abzan)
Theres a significant artifact theme among these cards and theyre dissonant enough from the main set that I wanted to highlight them separately the way that I did with The Jurassic World Collection
In my case, I'll be seizing the opportunity to acquire as many fetches as possible, along with some of the Titans
