Nazahn, Revered Bladesmith
The tutor is the whole design conceit here: a legendary creature that fetches an Equipment on entry, but plays favorites with its own signature weapon. Reveal anything else and it lands in your hand as ordinary card advantage; reveal Hammer of Nazahn and it goes straight onto the battlefield, ready to attach. That asymmetry is the point. The card is a two-piece engine that ships with a built-in tutor for its second half, collapsing the usual "find the payoff, then find the way to cast it" sequence into a single trigger. The Hammer's own indestructibility clause, granted to everything you equip, turns the 5/4 body into a resilient attacker rather than a fragile investment. The second ability rewards the plan you were already committing to: any equipped attacker taps down a blocker, which compounds fast once you are stacking gear across a voltron board. It is a builder's payoff rather than a standalone threat, asking you to have already assembled the toolbox it wants to fetch from. The lineage is old (creatures that tutor for a specific companion card have shown up across the game's history), but pairing the tutor with the tap-down aggression gives this one a clear offensive identity: it does not just find your gear, it turns the equipped board into a machine that keeps blockers off the table.
