When you planeswalk to Enigma Ridges, each player who controls fewer lands than the player who controls the most lands searches their library for a number of basic land cards less than or equal to the difference, reveals them, puts them into their hand, then shuffles.
Whenever chaos ensues, draw a card, then you may put a land card from your hand onto the battlefield.
