The Fertile Lands of Saulvinia

Whenever a player taps a land for mana, that player adds one mana of any type that land produced. Whenever chaos ensues, reveal cards from the top of your planar deck until you reveal a plane card. Chaos ensues on that plane. Then put all cards revealed this way on the bottom of your planar deck in any order.
