Rafa, The Legendary

Legendary Casting (As long as Rafa is in on the battlefield, your Legendary Sideboard is active.)

Legendary Bulk— Once each turn, you may cast a legendary permanent from your Legendary Sideboard as though it were in your hand. If you do, exile a land you control. Whenever a legendary permanent enters the battlefield under your control from outside the game, it gains haste and "When this permanent dies, shuffle it into your library."
