Mechan Navigator

Merfolk Looter and its lineage asked you to spend the creature's turn on the loot: tap it, get the filter, do nothing else. This one reverses the order. The trigger fires on the tap itself, wherever that tap comes from, so looting rides along on whatever else the creature was already committed to doing. Swing it into combat, crew a Vehicle, feed it to a convoke cost, tap it for a mana ability: each of those now filters a card. The 2/1 body is deliberately fragile, because the payoff is the act of turning it sideways, not the two points that land. A pilot that dies to the first blocker still got its loot the turn it attacked, which reframes filtering from a dedicated engine slot into a bonus the creature earns while working a second job. There is a wrinkle worth respecting in the filter's order: it is draw-then-discard, so you commit to seeing the new card before deciding what to pitch, which matters when you are stocking a graveyard on purpose rather than digging for an answer. Being an artifact as well as a creature opens cost-reduction and reanimation shells that key off artifacts, and the Pilot type builds a small loop, since crewing a Vehicle taps it and tapping it loots. The design is asking for a board that keeps inventing reasons to tap it.
