Decisions and interactions

Enchantments, card keywords and afflictionsSpending an event reward on a starter and then choosing Pandora's Box can erase that investment.Do transformations keep upgrades and enchantments?Pandora's Box transforms every Strike and Defend, so an enchanted starter is part of the cost of choosing it, even when its replacement is a more useful card.Miniscule: win with five or fewer cardsReach the final win with no more than five permanent cards. Budget removals, preserve a complete damage-and-defense package, and separate a tiny combat loop from a tiny final deck.
Pandora's Box

An upgraded target does not always stay upgraded

Permanent transformations of an upgraded, removable, eligible card. No extra upgrade-on-obtain relic changes the result.

  1. Ordinary random transformPandora's BoxUpgrade is lostThe original card is replaced by a fresh card. Its enchantment is also lost.
  2. Claws makes MaulMaulUpgraded target → Maul+This named Ancient conversion preserves upgrades and compatible enchantments.
  3. Archaic ToothArchaic ToothStarter upgrade preservedIts named starter conversion is another specific exception. Eligibility still matters.
Compatible does not mean every enchantment. Spiral is restricted to basic Strikes and Defends, and cannot be carried onto Maul.
