Conjurer's Mantle

Most tribal card-advantage engines cost mana every turn and sit off to the side of the board, a separate lever you pull instead of a payoff for doing what the deck already wants. This equipment folds the engine into the attack step: the +1/+1 and vigilance mean the wearer swings and holds the fort at once, and the dig fires on that attack rather than on some extra activation, so refueling costs you nothing beyond the aggression you were already committing to. Six cards deep is a wide look, but the payload is gated on creature-type overlap; you cannot grab whatever you want, only another member of the tribe your creature belongs to. Equip a Goblin and you find Goblins, equip a Wizard and you find Wizards, so the yield tracks how densely you have committed to one shared type. That gating keeps the broad dig in check, and it explains why the card offers almost nothing to a board of unrelated singletons. The random-bottoming clause adds a second cost: you see six, take one, and forfeit the ordering on everything you leave behind, so this is dig, not library sculpting. The lineage runs through white's long tradition of turning combat into card flow, but the reward here is deliberately narrow, built for a deck stacked on a single shared type rather than a generic aggro shell that happens to attack.
