Atterfalls Temple

Atterfalls Temple comes into the battlefield tapped.
At the beginning of your turn, you gain life equal to
the number of artifacts and basic lands under your
control. As long as there are two or more other
players still in the game, you and spells under your
control can not be targeted.

{t}: Add {x} to your mana pool and gain X life,
where X is the number of artifacts and basic lands
under your control.
