Clef, Geomancer Ascendant

Trample
Whenever Clef attacks, destroy a land at random.
If it was nonbasic, each player draws 3 cards, then discards a card at random. If it was a land you controlled, each player sacrifices a permanent at random, chooses a permanent type at random,
reveals cards from the top of their library until
they reveal a card of the chosen type, and puts it
onto the battlefield. Each player shuffles the rest
into their libraries.
