Given the nature of the game, I assumed there wouldn't be conjurations at all. And it would make sense to eliminate armour, too, since the desired match length is about 30 min. Basically, there's no such thing as a slow deck or long-term strategy, and you want to reduce the number of card types, so no need for extra channeling, walls, temples/totems/spawn points, etc. I could see doing away with equipment entirely, but the box art shows typical weapons for the mages. Perhaps weapons could be included as mage traits on their cards, similar to the way a Warlock or Beastmaster has Battle Skill or Archer Skill granting +1 melee/ranged.
