Mojave Desert (Black Lotus Unknown Planechase PLA030) - Common

Whenever you planeswalk here, each player searches their library for up to two basic land or Desert cards and puts them onto the battlefield tapped, then shuffles their library. If a Desert entered the battlefield under a player's control this way, they create a 1/1 black Snake creature token with deathtouch.
Whenever Chaos ensues, create X 1/1 black Snake creature token with deathtouch, where X is 1 plus the number of nonbasic land types among lands that player controls.
