Cairn Wanderer’s ability looks at all cards in all graveyards. It gains any landwalk abilities and any protection abilities.
Changeling (This card is every creature type.)
As long as a creature card with flying is in a graveyard, this creature has flying. The same is true for fear, first strike, double strike, deathtouch, haste, landwalk, lifelink, protection, reach, trample, shroud, and vigilance.
