The trade here is the interesting part: to buy back an instant or sorcery, you have to feed a creature card from your graveyard into exile. Most spell recursion on a body asks for nothing beyond the mana; this one demands you spend graveyard resources to reclaim graveyard resources, which turns the recursion into a question of what you can afford to lose. In a deck stocked with cheap creatures that have already done their work, the exile clause is nearly free, and the return trigger conditions on it: no creature to exile, no card back. That chaining ("when you do") means the whole engine collapses if your graveyard is empty of bodies, so the card is only as good as the yard you have built for it. The body itself is a modest 3/2, which frames the creature as a value piece that happens to attack rather than a threat that happens to recur spells. What it recovers is the flexible half of a spellbook: a counter, a burn spell, a card-draw, whatever the moment wants, pulled back at the cost of a creature you were done with. It is a self-mill and graveyard payoff wearing the clothes of a common tempo creature, rewarding decks that treat their graveyard as a second hand and their spent creatures as fuel rather than casualties.
