Totem-Guide Hartebeest

A tutor wearing a body that wants to block. Aura decks live and die on consistency: the deck is a pile of enchantments stapled to a single creature, and if that creature dies before the Auras land, the whole stack of card advantage goes with it. This addresses both halves of that problem at once. The fetch turns any Aura in the deck into a guaranteed find, smoothing the variance that otherwise makes the strategy a coin flip, while the 2/5 frame walls early ground so the next threat has time to suit up. The search is throttled in three directions: it puts the card in hand rather than onto the battlefield, so you still pay to cast the Aura afterward; it reads only Auras, so it does nothing in any other shell; and it rides on a five-mana creature rather than a cheap spell, so you front-load the entire cost before the digging pays off. That narrow target is the feature, not the tax. A tutor restricted to a single card type can afford to be unconditional within that type, and a creature-based one needs that restriction to keep it from sliding into every value deck that wants a fetch on legs. The toughness is where the value lives: five toughness eats most early aggressive starts and buys an Aura deck the turns it needs to assemble its haymaker without overcommitting the enchantments early.
