Sun-Blessed Mount

Almost the entire text here is a tutor for one specific card, the rare design where the body is the afterthought and the search is the point. The 4/4 Dinosaur is a serviceable enough attacker, but the enters trigger exists to assemble a two-card story: fetch Huatli, Dinosaur Knight from either library or graveyard, building toward the planeswalker's loyalty payoffs without spending a separate card to dig for her. Pulling from the graveyard as well as the deck is the wrinkle that gives the design its redundancy: a discarded or milled Huatli is not dead, just waiting for the next Mount to come down and recur her. That dual-zone search is also what keeps the package self-correcting, since you can run fewer copies of the planeswalker and still find her reliably. The structural lineage here is the named-tutor creature, a body that doubles as a deckbuilding constraint: it only matters if you are running the exact card it names, which is precisely the kind of build-around contract this trigger asks you to sign.
