Wall Of Trees is an Advanced Powercard in Bloons Card Storm. It grants the player's Hero 120 Shield and grants 2 Gold the next time their Hero's Shield is broken. This card can be played multiple times to stack the amount of Gold gained. It can only be used in Obyn Greenfoot decks.
Wall of Trees buffers against a small amount of bloons, while compensating Gold upon breaking. It's helpful on all stages of the game, and is essentially a stronger Mana Shield if the 2 Gold is refunded.
Wall of Trees can be combined with Nature's Clarity to maximize Obyn's shield.
