Storm Seeder

At the beginning of your end step, you may reveal your hand and put all land cards from it onto the battlefield. If you do, discard your hand.

Whenever a land enters, its controller creates a 1/1 green Snake creature token.

Each player may play an additional land during each of their turns. Whenever a land is tapped for mana, return it to its owner's hand.

Whenever you cast a creature spell, create a 3/3 green Beast creature token. Whenever you cast a noncreature spell, put three +1/+1 counters on target creature you control. Landfall — Whenever a land you control enters, you gain 3 life.
