Reforest

You may draw up to 2 cards in any combination from the plant deck and/or the nursery. Replenish the nursery between player turns. (Rulebook, p. 8)

Your first plant must be played at low elevation. Each later plant must be played adjacent to an existing plant or by covering one; a covering plant must be taller than the plant it covers. (Rulebook, p. 8)

Pay the cost using any combination of cards discarded from your hand and adjacent stored-energy cards; each discarded card counts as 1 nutrient regardless of its printed cost. Covering the topmost plant in a stack gives a succession discount by subtracting that plant’s cost from the new plant’s cost. (Rulebook, pp. 9–10)

No. A plant must be taller than the plant it covers, so plants of the same height cannot cover one another; there is no limit to the number of cards in a single stack. (Rulebook, pp. 10–11)

Flip the covered sun plant face down as stored energy. It no longer has its plant effects, but its visible understory information—including icons, traits, and plant value—still matters; stored energy can also be spent to pay for plants in adjacent spaces. (Rulebook, p. 11)

The round ends immediately, even if it interrupts the current action: resolve the round-end visitor, reset the deck and nursery, then let the player finish the interrupted turn or action. After the third round, play continues until it would be the starting player’s turn again, then scoring begins. (Rulebook, pp. 12–13)
