Blue's version of the payoff that turns an artifact deck's ambient noise into card selection. The trigger fires on any artifact entering, not just a spell you cast, so Treasure tokens, Clue tokens, artifact creatures, and equipment all count toward the loot. That distinction matters: the ability rewards a deck stuffed with cheap artifact churn rather than a few expensive bombs, and the loot (a draw paired with a mandatory discard once you've drawn) smooths draws without netting cards, which is why the effect could be handed to an evasive four-drop body without being pushed. The discard is the honest tax here; each trigger digs one card deep but demands you shed something, so it pays to have graveyard-hungry cards worth pitching rather than treating the loot as free acceleration. Flying on a 3/3 gives the engine a clock of its own, so the card is not purely a value piece marooned behind the wall of an artifact board. The lineage runs through the long line of artifact-matters loot engines, where blue historically supplies the card filtering that a wide artifact shell converts into consistency. The optional wording ("you may draw") is the quiet safeguard: when your hand is precious you simply decline, so the trigger never forces a bad discard on an empty grip.
