King of Nature

Unit counts and healing. Procreate adds units, Forests add HP every year and Mycelium keeps the spores it summoned from earlier battles.

High-difficulty build

Wall plan (Vao, updated for Patch #29): take Stone’s Wallmaker, whose walls gain 10% HP every year, and surround it with Forests for more HP. The Treant heals the walls, and Cauldrons with Venom supply the damage. Fight the King of Stone early to loot Wallmakers and Cauldrons.
Tank alternative: a Paladin between Forests, levelled by Overhaul, with Heartvine so the Treant heals beyond max HP.
Aevean: stack Banisher x3, skip the Boar and Elf combination unless it comes early, and take a Defender or Warlock from another king as the front line.
Perk: Tenacious gives a Procreate for every life lost.

Nature has the weakest agreement: two sources give different plans, and a third player says Nature cannot win far above King.

The first card is the base. You start a run with the base and 3 random cards from this deck.

Treant
Base
Creates a field on the ground that heals allies and damages enemies.
Elf
Troop
Ranged sniper. Always attacks the most distant target.
Boar
Troop
Can be mounted by adjacent troops. Each point of the Boar's HP increases rider stats.
Forest
Building
Every year, adds HP to adjacent plots (+2% per level on the official wiki table).
Mycelium
Building
Summons a fighting spore every few seconds in battle. Spores accumulate every battle.
Orchard
Tower
Creates roots that trap enemies. 3 roots per level.
Clone
Tome
Clones the card of the target plot.
Procreate
Tome
Adds 9 units to the target troop.
Poison Vial
Enchantment
Unit's attacks apply 3 poison stacks to the enemy (Patch #30).

Procreate adds 9 units to a troop; Fertility gives 5 Procreate cards.
Clone copies the card on the target plot. Players use it for the 9-of-a-kind achievements (9 Spires, 9 Dragon Dens).
Poison Vial applies 3 poison stacks per attack since Patch #30; Blight (1.0) adds a stack every year to troops carrying it.
Boar can be mounted by an adjacent troop and converts its HP into rider stats; a Ballista on a Boar earns Crossboar.
