The body is the giveaway: a 2/1 for three mana is below the curve for a creature meant to attack, which tells you this was never built to fight. The card-filtering trigger is the whole pitch. Looting on a stick has a long, quiet history in red as a way to smooth draws and feed graveyard payoffs, and stapling it to a cheap, expendable body is the common-rarity version of that idea: a creature you play for the rummage and are happy to chump-block with afterward. The trigger is optional and symmetrical in cost (one card for one card), so it does nothing for raw card advantage; what it buys is selection and, in the right shell, fuel. Discarding a fatty or a flashback spell turns the loot into a setup move rather than a wash, and the cheap body means you rarely feel the tempo. Outside of decks that actively want cards in the bin or a specific card in hand, it is a small effect attached to a fragile creature, which is exactly the rate a design like this is supposed to carry.
