Mechanics: The deck emphasizes artifact synergies and the energy mechanic, allowing players to accumulate and utilize energy counters to activate various abilities, reflecting the scientific and technological themes of the Fallout universe
Naturally, you'll want a deck full of angels, demons, and dragons to back Kaalia up
Never fear - it's in the deck
Esper decks also aren't out of the question with Edge of Eternities , as we get both Godless Shrine and Watery Grave in the half shockland cycle (although shocking yourself is not the best with Space-Time Anomaly)
It can also be Warped, meaning you can cast it for less, exile it at the end of the turn, and then summon it back later
That's a reusable engine, I also have the less synergetic Viscera Seer here too
