Arguments in the past against sets like Warhammer 40,000 or Fallout have been largely based on the high-tech setting, but when you compare it to the Brothers War , and MTGs history of using steampunk and aetherpunk, they dont feel a million miles apart
Candlekeep Sage seems the blue card of choice for Adrian, although in this space I think Shameless Charlatan is much better
She is all about dealing damage to other players, letting you draw cards if you dealt four damage to a player in a turn, and letting you do damage to players by casting noncreature spells with three or more mana

Numerous sets have been released, and alongside some sets there have even been extra releases, such as Illumineers Quest: Deep Trouble
