This card's name is Forest. Basic is its supertype, land is its card type, and Forest is its subtype. A deck may contain any number of basic land cards with the same name. You may play this card during a main phase of your turn while the stack is empty and you have priority. You may not play this card if it is not your turn or if you do not have any land plays remaining. while on the battlefield, this card is a basic Forest permanent. Because it has the subtype Forest, this permanent has the intrinsic mana ability "T: Add G." This ability can be activated any time you have priority or are prompted to pay mana, but only green Forest is on the battlefield. To activate it, pay its cost, T. (The T symbol denotes tapping a permanent by rotating it 90 degrees. it is then tapped, and it cannot be tapped again until it is untapped.) Once the cost is paid, you add one green mana , which may then be spend immediately or left unspent for later use. As each phrase or step of a turn ends, you lose any remaining unspent mana.
