Ancient Tortoise

Ancient Tortoise is a card that can be obtained once Area 8 is reached. It was added in Update 1.1.0. Largely neglected, its maximum Mana cost is a huge downside.In Update 1.1.6, its Ability was changed from "Summon: Your units cost 4." to "Summon: Your units cost 3." This marked the first time an Ability was changed.
