Frostpyre Arcanist

The interesting part isn't the recursion; it's the copy the recursion demands. The entry trigger doesn't return the spell in your graveyard, it fetches the other copy from your library, which means the card only works if you're running duplicates of the instants and sorceries you want back. That constraint reshapes deckbuilding around it: you don't play one flexible answer, you play multiples of a payoff worth doubling, so the Arcanist converts redundancy into inevitability. The 2/5 body carries the rest of the deal. A giant with that toughness is a genuine blocking wall while the value engine grinds, so the card can stall the board and refill the hand from a single slot without forcing a choice between the two. The cost reduction is generous on a creature that shares both its qualifying types, which turns the fetch into something closer to a four-mana enter-the-battlefield effect in the right shell. What keeps it grounded is that the trigger needs a matching card in your library: each trigger is a one-time dip, since every fetch thins your duplicates, and the graveyard-and-library symmetry means you can only pull back what you were disciplined enough to pack twice. It rewards a spell suite built with intent, where every card you want to see again is a card you were willing to run two of in the first place.
