Migration

Moves target to an empty adjacent plot. Moved card gains +10% damage and HP.

How players use it

King of Nomads Migration trick: surround the Warlord so only one empty plot is next to it, then move it out and back with Migration. The adjacent Mob gains a unit for every unit the Warlord gains, and Vao reports 12,000 units by year 30. Immigrant gives a Migration card at each expansion tower.
King of Nomads: Camp, Migration, Raptors and Dragon Den The King of Nomads unlocks after 99 troop cards used. Its cards reward placing and moving things: Camp buffs its neighbours whenever a card lands on an empty plot, Migration moves a plot and gives it +10% damage and HP, and the Warlord base shoots banners that lend its stats to allies. The base is not a fixed castle: you lose a life when enemies reach your life statues.
Balance changes in 1.0 Decree pools are 30% larger. Diversification no longer removes Rainbow cards from Rainbow encounters. Pillage now works with Razing, Offering, Chaos Offering and Chaos Mortgage. Havoc works with Migration.
