Druid Class [Dungeons & Dragons: Adventures in the Forgotten Realms]

(Gain the next level as a sorcery to add its ability.)

Whenever a land enters the battlefield under your control, you gain 1 life.

{2}{G}: Level 2
You may play an additional land on each of your turns.

{4}{G}: Level 3
When this Class becomes level 3, target land you control becomes a creature with haste and "This creature's power and toughness are each equal to the number of lands you control." It's still a land.
