When Mwonvuli Beast Tracker enters, search your library for a creature card with deathtouch, hexproof, reach, or trample and reveal it. Shuffle and put that card on top.

The creature card must have one of the listed abilities, not an ability that grants one of the listed abilities to the creature. For example, you couldn't put Prized Elephant, which has "{G}: Prized Elephant gains trample until end of turn," on top of your library this way.
