How players use it
- King of Time Aevean (November 2026) rates Kintsugi and the buffed Amplifier and reports a five-win streak on King IX IX before the late patches. That makes two sources. King of Time covers Amplifier and Portal rules.
- King of Time: Amplifier, Portal, Regression and Rewind The King of Time unlocks after 999 years played across all runs. Its deck turns the calendar into a resource: Portal sends the kingdom 2 years back at max level, so you replay those years’ councils, merchants and loot, and Amplifier copies the buffs it receives to neighbouring plots. Lives lost are not given back by time travel.
- Level cards from other pools Amplifier (Time): passes level-ups it receives to neighbours since Patch #23.
- Uses Test an interaction before relying on it. For example, put a Lab Rat between two Concabulators to see how a level-up chain resolves, or check what Amplifier passes on from each support building.
How to get it
- In the King of Time's 9-card deck: a run as this king can start with it, and losing a battle offers cards from your own deck.
- Loot after beating the King of Time in battle when that king is one of your enemies.
- Merchant: Jack of Structures (buildings, towers and bases).
- Joker mode: pick it for a custom deck.
